Finally gave this a go...
It takes a few levels before it gets good, but it does become pretty fun (Half Life 2)
I don't know if this is true of the PC version, but the game does have an annoying auto-aim (or something that can be described as close to an auto-aim) on any level that uses a vehicle.
Still a pretty good game, but I wouldn't rate it a 98%...I'm going to bump up the difficulty to see if that makes it more interesting.
