You might like Bioshock.  It was released in 2007, and is quite popular.  You’ll probably also enjoy Half-Life 2, which is similar.  Those are my two favorites.

Maybe Halo: Reach, it’s the latest game in the Halo series. It has a lot of cool features like the ability to jump really high and slide along the ground.
