Already compared by Kotaku to the joyous union of peanut butter and chocolate, Street Fighter X Tekken and Tekken X Street Fighter may serve to end a few arguments, and create many an unforgettable knock out. It's already obvious that Street Fighter X Tekken will be the horse to back. Using the artistic direction of Street Fighter IV, as well as the 2D orientation for battle, SFXT will be the Capcom fighting fan's game of choice. It also appears as though there will be a tag team element to this fighter, however given reports that a retail release is two years away, I probably shouldn't get too excited about that yet.
As for what Tekken X Street Fighter means for fighting game fans is yet to be deciphered. While it is reported to play more like Tekken (obviously), the mechanics behind the hadouken in a 3D environment are yet to be revealed. I hypothesize that it will be similar to the flash of light seen in the regrettable (so bad it's awesome) 1994 film interpretation starring Jean-Claude Van Damme (about 35 seconds into the video below). Pax Bisonica! If not, it will be probably be a charged, unblockable move with lots of pyrotechnics.
Just when I thought that I had seen it all, Thor has since been added to the roster of Marvel VS Capcom 3: Fate of Two Worlds. I normally prefer my Street Fighter experience to be less on the crazy side, but sometimes you need to super jump over your opponent and hit them with a Level 3 Hyper Combo Finish!
What is your dream crossover event? Mine is already on the cards!
