I dont think their games are anywhere close to amazing, you enjoy them and a lot of others do, great! You want MK games, cool, theres a shitload of them and they are made in a very particular way that is antithetical to EVERYTHING a Virtua Fighter game is about, regardless of quality. Its not something that fans want and its been made pretty clear in this thread. I dont want Nintendo making Last of Us either, btw, and I love both companies.
NRS will continue their cycle of MK and Injustice games for the foreseeable future, with Injustice clearly being their experimentation heavy game.
Its not gonna happen and its a bad fit. Not everything is about sales. VF5 was a great game at the wrong time, thats all. Sega is a company not tied to the IP because they have a lot of avenues to make games in (not the same for NRS, Capcom, SNK or Namco, btw, so when the time is right they'll bring it back on their own terms, not by giving it to Warner Brothers.
