I usually wait for the bargain bin, or gold/platinum/whathaveyou editions where I get expansion packs bundled in, so I'm in effect buying more than just one game in terms of content. The only games with which I didn't wait for the price drop were the TW games (all of them; damn shame I didn't wait with RTW), Baldur's Gate 2, and Morrowind. Everything else is not that intriguing that it couldn't wait for the discount. I also think that most games today are overpriced.
