Video game crossovers you love/want.

Tell us about some video game crossovers you'd love to see, or have played and liked.

I've always liked the SSB series, as many others have and I think it's a cool crossover of all the Nintendo characters and some third parties.

I'd also love to see a Phoenix Wright vs Ghost Trick crossover, since the creator of both said he'd love to make one, and it would be awesome and the best game ever created.

I think that Sega should make their own version of Smash Bros too. I'd love to see a story mode in there as well as an interesting fighting style of the characters, I can see it now. It could start by Eggman taking the Master Emerald only for Sonic to fight him and then as he slips away

Spoiler

he gets attacked by the Blue Rouge's, gets boarded and they take the Emerald for themselves thinking it's a Moon Crystal, then Sonic finds out and tried to get it back. Hilarity ensues

So what about you guys, what kind of cross overs would you like to see?
