Gun to my dick, I'd go with MK vs Marvel.
They've been violent before, they can be violent again.
MK vs Street Fighter.
For 3 reasons really:
1. I want Juri and El Fuerte in MK.
2. I'd love to see Street Fighter characters perform fatalities. :3 Just thinking about it makes me hyped.
3. I wanna be able to rip Dhalsim's arms out and blow up Ryu's head.
MK Vs Killer Instinct, obviously. KI also has fatalities and Ultra Combos are basically brutalities. Also has Humiliation, Stage Fatalities... And both Jago and Fulgore rock!
Mortal Kombat vs Street Fighter. I have waited twenty long years for this game, and I'm prepared to wait as long as I need to...but it WILL happen, and it will be glorious.
Never say never my friend.No it will NEVER happen. No matter what you think or hope, it will never happen. Capcom would never allow blood and guts in their game and especially fatalities done on their characters.
I wouldn't mind a Mortal Kombat vs. Tekken. Also, give the Tekken characters their own fatalities in it. That could be interesting.
I, personally, wouldn't mind a Brutal Legend Crossover.
