How do you know? Do you have the sales figures? Do you know how big the budget was? What was their break even? No. You don't know if it failed, flopped or anything that so just **bleep**. I've heard that it sold 500k units by the middle-end of January, so if my math is correct then they still made a good bit of money (average of $40-$50, taking into consideration the early price drop) . From where I'm standing, the game did not look like it had a big budget to begin with considering the size of the development team, the amount of characters and the little amount of content. If anything this game has done quite well.
To plug my league like I always do...
But seriously, some of the fights I have seen rival certain fighting games. SuperBot made one heck of a game, just try to watch some really high level play and you'd see there is a lot more to this game then we have found thus far, you should hear about some of the tech we discover EVERY day at the leagues! The meta game is VERY interesting, and DLC just ads to it.
