The series ended before the kids got home, unfortunately. And as we know, our favorite cartoon often borrowed heavily from other stories, fables, and movies in many of its episodes. So, with that in mind, based on some other stories/series (some popular, some more obscure), here are some ways that the series MIGHT have ended...

The "Help me take this silly one-horned helmet off," ending (the Star Wars Trilogy):
Venger redeems himself, saving his son from the Great Evil No-Name. He's killed in the process, of course, but justice and goodness prevail. Who's his son? Why, Hank, of course!
Hank: "Nooooooooooooooooo!!!"

The "But it WAS a real live place!" ending (The Wizard of Oz):
Dungeonmaster gets the kids to chant "There's no place like earth, there's no place like Earth," over and over. After some cool psychedelic effects the kids wake up in the hospital, where they'd been sent after a big dragon statue had squashed their coaster car. They try to convince their doctors (who look remarkably like DM and Venger) that their Realm adventures really happened.

The "All men die, but few men truly live" ending (Braveheart):
The kids are killed off by the evil Venger, while they are trying to rally the masses to fight one last huge battle. But instead of discouraging a revolution, this tragedy is enough to incite the peasants to revolt. They fought like warrior-poets. They fought like Scottsmen. And they won their freedom. (Insert inspirational bagpipe music here).

The "Ziggy sez you have to..." ending (Quantum Leap):
The kids, after finishing all the tasks DM had set for them, enter the portal and discover themselves in another world!! And not only that, but they are trapped in different bodies! A man appears before them with a calculator that makes ridiculous noises and tells them that they have to set right the wrongs of these people before they can leap home.
Hank: "Oh, boy..."

The "'Scuse me...but why does God need a spaceship?" ending (Star Trek V):
The kids discover that DM is really an evil god who's been using them to take out his enemies! They decide they don't want to play this little game anymore. DM grudgingly sends them home and picks six more gullible kids to do his dirty work.

The "Last time, it snowed for ten years!" ending (The Lion, the Witch, and the Wardrobe, by C.S.Lewis):
After a teriffic battle, Venger is finally defeated by DM (who's taken the form of a big lion). DM installs the kids as rulers of the Realm, and they grow up to be wise (yet still homesick) adults. One day, while they are travelling through a forest searching for a magic stag that will grant them all a wish, they stumble upon a coaster car which takes them home. They find that no time has passed and that they are kids again.

The "Why son, you're forgettin' yer wind-up mushroom!" ending (Dangermouse):
The big guy whose name can't be spoken comes back and takes Venger and his five-headed pet dragon away after giving him a good scolding. The kids find out that Venger was just a big kid, No-Name was his daddy, and that the Realm was the cosmic equivalent of his G.I.Joe action figure playset!

The "We must all plant our gardens" ending (Candide, by Voltaire):
Bitter and disillusioned after years of following DM's advice, but never getting anywhere, the kids turn their weapons over to Venger. They settle down in a small cottage together, discussing philosophy. Venger, now ruler of the Realm, drops by every now and then for Earth-style pizza and home-grown cucumber sandwiches.

The "Rip Van Winkle" ending (a.k.a. the Murphey's Law ending):
The kids make it home in time for their retirement, just as Eric predicted. Three die of heart attacks on the exciting ride back and two more die of shock upon returning and finding out that no time has passed on earth. The last one spends the last few years of his life trying to convince his rich dad that he really is Eric.

The Soap Opera ending
It doesn't ever end, it just gets sillier and sillier...but it's so addictive, you have to watch it every day or suffer withdrawl. "Diana leaves Eric for a younger man...a MUCH younger man!! (Diana: "Sorry, Eric- I need someone with my keen fashion sense...someone less whiny than you!") But this is nothing compared to the drama when Hank finds out who the REAL father of Sheila's baby is!!! (Hank: "But Sheila...he's not even HUMAN!!") Presto rips a hole in the fabric of space time when Uni tries to teach him to teleport! (DM: "Tsk, tsk, tsk...too much twiddle!!") Will the Realm recover from the disaster? Will the kids ever make it home alive? Find out on tomorrow's exciting episode of The Young and the Restless in Another World!"

And of course, "This is the song that never ends...yes it goes on and on my friend..." (song from Lamb Chops, but the ending itself is in the spirit of all series such as Gilligan's Island, Land of the Lost, Lost in Space, Star Trek Voyager........):
The kids never get home-- they are stranded until low ratings kill them!

The "And it would have worked too, if it wasn't for those meddling kids... and their pesky unicorn!" ending (Scooby Doo):
After spending three years in the Realm running for their lives, the kids finally come to their senses and realize that there are no such things as monsters, wizards, and time-travelling Nazis. They split up and search for Venger. Once they find him, a wild chase ensues. At the end of the chase, the kids manage to turn the tables on Venger and end up capturing him. They remove his mask to reveal that he's really a real estate developer named Bob (who has a thing for wearing dresses). The D&D ride, the Realm, etc., were just part of an elaborate (not to mention ridiculously expensive) scheme to scare people away from the amusement park so that Bob could tear it down and build a mega-mall in its place. With Bob safely in custody, the kids return home, buy a cheesy-looking 70's van, and become full-time detectives.

The "Pawns of Greater Powers" ending (Elric of Melniboné):
The kids realize that the main reason they are stuck in the Realm is that Dungeonmaster is using them as pawns in his conflict against Venger. They decide that the only way to end the conflict and get home (and set the Realm free in the process) is to destroy both Venger and Dungeonmaster. The kids eventually kill Venger, Dungeonmaster, and Tiamat (just for good measure) in a final, cataclysmic battle. As the kids are resting and recovering from the battle, their weapons turn against them and they are all killed off. As they lie there dying, they see their weapons combine and turn into a large, demonic being. Just before they die, each realizes that by attempting to free themselves and the Realm, they have doomed the Realm to enslavement. The creature, which used the kids as its pawns, now has no one to oppose it. It flys off into the night with the parting words, “Farewell my friends. I was a thousand times more evil than thou!”

The "Back to Reality" ending (Red Dwarf):
The episode starts with the kids fighting an evil wizard. Just as it seems that the kids are going to win, the wizard casts one last spell and slips away. The kids are engulfed in a foul cloud. One by one, they all drop and “die”. They awaken to find themselves hooked into a computer. They find out that for the last three years they have been playing a complex virtual reality game. The kids must now re-adjust to real life. Unfortunately, the “kids” find out that in real life they are very different people than who they were in the game. In fact, the reason why they played the game in the first place was to escape who they were! Hank finds out that he’s an impeached politician; someone who’s been proven to be a terrible leader. Sheila is an “old maid” who spends almost all of her time alone. Bobby is a cowardly teenager who’s been picked on his whole life. Presto is a guy who’s dumb as a rock and always wished he could’ve amounted to something in life. Diana is an old woman who wants to desperately regain her youth. Eric has been dirt poor his whole life, and always wanted to be someone of wealth and privalege. After experiencing the game, none of them can bear to return to real life. They all decide to commit suicide together. Just as they’re about to commit the act, they re-awaken in the Realm. Dungeonmaster explains that the spell the wizard cast was a “Cloud of Despair” spell, and that they were all suffering from a group hallucination. Dungeonmaster saved them just in time. The kids are relieved, but no closer to getting home. (OK- this isn’t a real ending, but the way the episode is set up, until the kids reawaken in the Realm, the audience is supposed to believe that this is the real ending to the series... hey, it worked in Red Dwarf...).

The "D&D 1990" ending (Battlestar Galactica / Galactica 1980):
After a decade or so off the air, the network execs at CBS figure out that there are still a lot of old D&D fans out there. They decide to start the show up once again, calling it "D&D 1990", but give it a much smaller budget than the original. Due to the smaller budget, they have to hire less expensive voice actors. Since all the voices have changed, the network execs decide to have the writers change to a whole new cast of characters. They do, however, decide to keep Venger and Dungeonmaster, but only for continuity reasons. The execs also decide that the special effects for the Realm are too expensive, so they decide to move the action to Earth (I know that it's a cartoon, so it shouldn't really matter, but try explaining that to the execs). So the kids (now with new names, faces, and voices, but still with the same basic personalities) finally manage to get home, but have inadvertantly brought Venger and his minions with them. They spend the next nine episodes fighting Venger and trying to protect Earth. They fly around on pegasi, use archaic weapons, and cast spells, yet none of the normal Earthlings ever seems to notice. The whole show is a fiasco and becomes the laughingstock of the industry. In order to boost the abysmal ratings, the network execs decide to spend the money to rehire Willy Ames to do the voice of Hank. Unfortunately, it's too little, too late. Even the return of Hank can't save the show. D&D 1990 is cancelled after only 10 episodes. The fans are still out there, however, and early in the 00's rumours start to fly about a new version of the series on the FOX network...

Endings by Andrew "Tovanan" O.:

The "To Hell With It" Ending
Our heroes recover some magical device that will alow them to return home. However, in using it they must leave it behind. If they do, Venger will appropriate it and wreak havoc and destruction on the Realm. "Hell with it" they say, shrugging their shoulders and stepping through the gate.

The "Real D&D" Ending
The kids inadvertently stumble into one of the original extremely-difficult D&D role-playing modules such as Tomb Of Horrors, Isle of Ape or The 384th Incarnation of Bigby's Tomb, where they are killed outright.

The "Don't Turn Your Back On The Unicorn" Ending
While the kids sleep around the campfire, Uni is magically possessed by Venger and spears them all through the head with her horn one after the other.
