I pretty much always buy games on faith alone. Reviews aren't much help, if a game from a major studio is basically functional and doesn't set fire to anything it gets 90%. But then I can afford to get burned now and then, If I couldn't... Well I pretty much always buy games on sale these days anyway. Holding to that more strictly and seeing if it is fundamentally broken is probably a good idea.
