I don't get much a year, so I usually wait until the game price drops at least half-way to get it. I mean, I got three games that I love back in March. They came out early-to-mid last year. They're still the same game. They're good. They're fun, enjoyable. Age doesn't affect that. And I can get three times as many of these good games as if I bought them when they came out originally.
Honestly, I'd probably buy more games when they release if they game out for less than 60 bucks. I mean, who are they trying to fool, some developers? I hate to be mean, but they know when they're releasing a game that isn't worth $60 (here in America anyways). If, say, Aliens vs Predators, released at $30 instead of $60, I think that they'd actually make more money than they did with their full sixty price-tag.
