i’'l bite
Dc vs marvel
GG vs darkstalkers(wasnt arc made up of former employees of capcom who worked on DS series?)
Mario vs sonic
a rocker version of Def jam vendetta with focus on classic 60-80s bands:
Transformers vs SF. --You could have some BS story excuse to shrink down the TFs to near human size, and have it play like mvc1.
a Blaxploitation /70s icons fighter, with shaft, coffy, supafly, etc with customizable accessories and play like Tekken.
Still waiting for Guilty Gear vs Darkstalker, we all know that this can be awesome.
marvel vs. jojo
DC vs. DBZ
Nintendo vs. Marvel
EBA vs. Ouendan
CN vs. Nick
This could happen.
Myself, I’d like to see a Destrega vs. Dragon Ball or Destrega Vs. Power Stone crossover. How’s that for obscure?
The best thing ever would be Capcom vs. SNK, I mean could you guys imagine?
Don’t do Sammy vs Capcom. Shits gotta be Arc System Works vs Capcom. DarkStalkers and Guilty Gear are a perfect fit. The rest just has to be there to be awesome. Imagine Guilty Gear CCs…? Delicious… 
Guilty Gear vs SNK
That would make my year.
MvC3. done…
I’ll probably be in the minority, but I’d love to see Arc Systems Works or Capcom work their magic on Ranma 1/2 game, versus style. 2nd choice would be an all out anime crossover battle, which would allow Capcom to sneak in Darkstalkers and Street Fighter and finally put Vampire Hunter D in a game that doesn’t suck.
After seeing the Super Beam hadoukens in the MVC series, I’ve always wanted to see DBZ vs. SF. Goku/Ryu vs. Vegeta/Akuma!
My god, i was just thinking this same shit some days ago. Ranma needs a decent 2D fighting game comeback like YESTERDAY.
Tobal 2 vs Ehrgeiz vs Power Stone
I love how the Dragon Ball characters look like Hobbits next to the Street Fighter characters.
Has anyone mentioned Sega vs. Namco yet?
I’d prefer an all-new concept for all fighters. Kinda burnt out on needless crossovers.
And I’m not a storyline nerd or anything, but I can’t think of a single reason why Ryu would want to punch Superman in the face.
And fuck MUGEN. It’s lopsided shit. You can download a Ken that uses Alpha 3 engine by himself… and put him agaisnt Ken that uses MvC2 complete with super-jumping off-screen. Then there is always people who are like “OMG AKUMA ROX” and so they make his shoryu take 90%. Ragedocious!
Popeye’s vs. KFC
Teyandee.
hmm, since capcom did have the rights to make disney games it would be cool to see capcom vs disney.
horned king with scar assist ftw!!!
Vampire Savior Vs Guilty Gear
