This does look pretty cool. I'll have to check it out.
Wasn't there just one Killer Instinct game? If so that doesn't make a franchise just a game.
There are 2 Killer Instinct games, 3 if you count KI Gold, but I'm pretty sure it's identical to KI2.
And while MK has always been more popular, KI has much more depth. I've always felt it to be a far superior game. It's funky how it bombed as badly as it did.
