Actually, I have a more specific one. If I wasn't interested in it when it came out, then there's no reason why I ought to be interested now. Life's too short, and good games are coming out all the time. Might as well support the games I want to play now. Examples of this will be buying Valkyrie Profile: Silmeria and Suikoden V right off the bat, but turning a blind eye to older games I had been meaning to check out until now, like the Phantasy Star and Star Ocean series. If it came out before the beginning of 2006, I'm not even going to worry about it.
And relating to that:
1) If I can't find it new, from a retailer, then it's a lost cause
2) If the price drops to $30, that's just fine and I'll buy it rather than waiting for it to hit the gutter
