What Game Crossovers would you like to see?

[Shaggy]

Alright. I was searching on gametrailers.com yesterday when I came across a game that stars both Spyro and Crash. I thought this was pretty weird that they are bringing these two game figures together for one game. What kind of crossovers like this would you like to see? I think it woudl be cool to bring Ratchet and Clank into the Jak and Daxter universe or Jak and Daxter into the R&C universe. What do yall think?

Just Final Fantasy characters appearing in other Squaresoft RPG's as guest characters and stuff.

Not just the name but the actual same character.

[Hired Hitman]

things that have to do with the same area, i.e. jungle > donkey kong, space > that starfox dude. etc.

you know :-\

Street Fighter vs Mortal Kombat would be pretty bad ass.

Or Street Fighter and Final Fight only instead of Final Fight guys being in street Fighter, it's the other way round.

Double Dragon vs Final Fight.

Final Fight Vs. Streets of Fury
Doom Vs. Quake <-- Would be lame, but would sell
Final Phantasy Star
F-zero and Wipeout
