True, I don't think it's bad necessarily, but I don't think it's good either. This is where the slippery slope stuff starts happening with people just taking your money because they see the opportunity to do so.
Part of the whole kickstarter-gaming thing was to make games that would never be created otherwise, actually happen. If a game was already greenlit, being made, and would presumably find release....it becomes a kickstarter to improve the quality of the game through a larger budget, which is fine but it's different angle for sure and can get into some shady territory quickly since there's no real way to determine if the extra money was actually put to use or just pocketed.
