Good... just not as good as the original.

The game itself did have the whole gravity gun thing which hasn't been done before in a FPS, well like to this standard anyways. It really adds a fantastic touch to the game but without the enemy having them and stupid AI it really makes it less fun. At E3 03 they showed how good the AI was but it didn't turn out anything like that which was a shame.
The game is average length for a FPS game and the additions of CS and other games coming with it + the mod community really makes it great value. The mod community also can change all skins and sounds in the game + interface and more so it really does mean the graphics and sounds could be anything you want.
The variation of levels is very good too altho there were some that felt rushed and just not fun to play. which is also a problem on the expansion too. I love the sounds and stuff, my fave touch is the siren noises that are like whale calls :) The story ends at a cliff hanger which is obviously setup for the episode content, they've planned this for longer than they let on.
Anyways overall its a fantastic game but not as good as the first because it doesn't have a big impact like the first. It's still fun though but the AI really lets the game down IMO.
