Especially when you consider that for most console releases, it's cheaper to buy things on PC. So if I can buy a new game on 360 for $60, and the same game on PC for $50, he should be charging $10 for his game on PC. Or $5. Or, you know, make it freeware like the dozens of deep, lasting, or legendary games we've got already that cost absolutely nothing and which provide more gameplay. I don't understand why people don't realize that you need to give people a reason to buy your game. I mean, you need a compelling reason, plain and simple, and you certainly can't expect to jack up your price for absolutely no consumer-centric reason. Braid's concept may be unique and cool, but it isn't that amazing. It's just another puzzle game with its own twist, which is fine; but you can only get away with calling a short, mildly clever puzzle game astounding and innovative if you're Valve.
Besides that, when you delay the release as long as he did for one platform you have to expect excitement to be at an all-time low. Tons of PC gamers haven't played Braid, but we've already seen a lot of what makes it special. What's to get all worked up about now? Playing a game everybody else was done being excited about last year? Of course that's not everything, especially not to anyone who plays games for the experience rather than getting into the mob mentality, but if you don't consider momentum as a game developer or publisher, you're pretty stupid.
EDIT - Er, that was in response to Idol's post. You other people post stuff faster than I do.
