Thoughts on Buying Video Games

The thing about video games is that there is really no way that the price of a game will ever rise, because there are always newer and better games being released. Aswell, with increased competition in the trade-in game market (EB Games, Futureshop, Best Buy, Blockbuster, Microplay, etc.) the prices are starting to drop at a faster rate then we've ever seen. An example of this is Brutal Legend. It made it's debut at $69.99 in October 2009, and by May of 2010 the price had dropped to $15-20. When I consider buying a game, I usually set a price point at which to pick it up, and when it hits that price point I make the purchase. It's a shame to lose half the value of the game within 3 months of buying it, so I would wait until it's on sale rather than paying $70. Of course, there are some exceptions, like Call of Duty 4, which has held it's value for what? 2-3 years now?
