If you have a PS3 or are going to get one, do yourself a favor and get Uncharted 2: Among Thieves. It's the sequel to the wildly popular Uncharted: Drake's Fortune game and both games are made for PS3 only.
Uncharted 2 was released in October 2009 and brisk sales held it at $50 or more for a long time. Only this summer did Amazon drop the list price from $59.99 to $39.99. And it's still kicking butt in Amazon bestseller rankings: last time I checked, #39 overall video games, #9 among PS3 games, and #1 among role-playing PS3 games.
