I'm gonna say I do NOT like this idea of SFvsTk and TkvsSF versions. Capcom is already really bad about dlc and monetizing everything. They've gotten pretty terrible. Idk how they will affect the namco part of it but I'm already staying away from this game. The MVC3 dlc has pissed me off to no end. And the SS4 stuff was pretty terrible already. So I'd expect to get a game with less than 20 people and like 6 on disc dlc. I hate when companies try to squeeze out so much. I know it's their purpose but there is a line.
So I don't want Capcom to touch my MK. Plus this two versions of the same game just seems like a problem waiting to happen. Major fans are going to be buying both and it's going to be like if you want to play with friends there's four possibilities.
Wanna play a game? Let's play online!

PS3 or Xbox (Well I just lost some friends like usual)

PS3 TkvsSF, PS3 SFvsTk, Xbox TkvsSF, Xbox SFvsTk (Really?)
So basically I F'ing hate Capcom because they have repeatedly crossed a line and have abused their fan base. And I don't want them to get anywhere near MK. Also the guy that made Street Fight does not like MK lol. But a tiny part of me wants to be able to show 18 different fatalities of Ryu to some of those hardcore SF fans.
Tekken I would not be as opposed to tbh, and I could almost see Soul Calibur taking an MK character in and MAYBE a crossover attempt spawning from that.
If you want to find a crossover think of something gory that people die a lot in and isn't a fighting game. There may not be something dead on fighting but something close could be thought of.
sorry this is so long. I really hate Capcom lol
