Okay so it's not "new" but it was a resuscitated IP with a remake of the original being handled by the same guys doing this one. The remake was really good. The sequel was not as smooth but I loved it and I easily thought a lot of the original ideas could have become a much better game if they got the chance to do an improved sequel, which the ending teased at.
Then the game bombed and the devs got shut down.
At least Spencer appeared in MvC3, and kicked major ass in it.
