Once upon a time, fighting game giants refused to work with one another, instead competing for attention in the arcades with their own individual products. But then someone got the crazy notion, “Hey, we should team up our franchises and see what comes up.” And thus, crossovers was born. Many companies have done it, including Capcom and SNK with their Capcom vs. SNK games, respectively, and soon Street Fighter x Tekken will be knocking around the streets, set for a release tomorrow. But are you possibly ready for…Sega versus Tecmo?
