So, I'm planning to eventually, someday, run a Robotech-Rifts crossover game (where the SDF-3 crashes on Rifts Earth).  Now, that's a pretty small jump as far as combining two games is concerned. I mean, they're the same system, they both use giant robots, etc etc.

But it got me to thinking, what other kinds of RPGs could you try to combine in some way or another, and what would the result look like?

I mean, what would you get if you crossed over Call of Cthulhu and Star Wars? Jedi facing horrible entities from beyond reality.

Space: 1889 and Coyote Trail? Sky Pirates of Deadwood!

Pendragon and Traveller? King Arthur and his space-knights fighting off the barbarian hordes in the dying days of the Imperium?

What other combos can we make?

No, Jedi who manifest powers derived from horrible entities from beyond reality.

Very nice.  The Victorians were deeply enamored with tales of the Wild West, so this is a rather natural (and strangely absent from the original Space: 1889) combo.

QuotePendragon and Traveller?

Camelot 3000.

Someone else here already suggested something like this a couple of weeks back (but I forget whom -- sorry), but D&D plus Blue Planet plus Traveller -- Gulliver's Traveller.  An endless sea of island after island of adventure.

!i!

What I actually played in was a CP2020/Shadowrun crossover - the European dominated CP2020 world with all its crazy gadgets and its roll&shout system, but with elves and shamans.
It worked well, and I've put the opportunity to a max with a human Erzulie mambo who has undergone an Elf exotic conversions together with a shitload of CP2020-specific implanted fashionware like techhair and chemoskin. It wasn't a big jump though.

What of the old Squad Leader meets D&D?

This is slightly off topic, but I had an idea for a Flash game which combines Dungeons and Dragons and mini-golf: the balls are characters, monsters and dungeon walls are obstacles, the characters have different classes which interact with the obstacles in different ways eg clerics destroy undead, thieves reveal secret doors etc).

Space Station 5 and Cinderella.

For my daughter, a Faeries Tale game where the Faeries had to help Cinderella save the Prince and the kingdom from the evil step mom, evil step sisters, and misc. evil goblins and trolls. The bad guys were going to take over at the Ball by infecting people with bad dancing. The only weapon/cure was good dance, the only way to fight was 'the dance off'.

Well, and there is that thing about a chase scene involving carriages.

I've tinkered with/made notes for something titled 28 Daycycles Later which steals wholeheartedly from the "zombie" movie of the similar name and throws it into a Star Wars setting.

Jedi + zombies = pretty freakin' cool in my book.

I once ran a game, where I combined ALL the game lines of the (old) World of Darkness (including the conflicting metaphysics) into one wild, no-holds-barred romp for the fate of the universe(TM).

The result was similar to what you might get, if you abducted David Lynch, tied him up in your cellar, beat him with a club made of used hypodermic needles, while simultaneously force-feeding him LSD. And than having him make a movie based on that experience.

The players say it was one of the best campaigns they have ever experienced.
