I feel bad for them, but did anyone HONESTLY expect this game to be a smash hit? At some point, these developers and publishers need to get realistic about what sells and what doesn't. While this game seemed well playing enough, it was destined to failure when they slapped the 60 dollar price tag on it instead of making it a low cost downloadable game.
I'm sure the developers were being realistic. You don't see them making some kind of bitter outcry about it. It's the audience that are not being realistic, with their "smash bros killer" mindset and thinking devs always have the time and funding to make every single idea they have into something that will blow everyone's minds.
