Nah, didn't get the ID Pack on Steam, I haven't really been fond of their post John Romero output.

If you feel a game is too short, generally that means that you really enjoyed it - So I think the inverse might be true with Doom 3.

It looked pretty nice thanks to John Carmack's ability to create incredible graphics engines,  and the atmosphere was great, but frankly the gameplay was lazy. Constantly needing to switch from your weapon to flashlight, and spawning monsters behind you frequently do not a good game make.
