This is awesome for the price, even if you already own Doom 3. The only disappointment is the requirement for Steam because I still do not trust Valve, but it's alright if you're worried about damaging the disc. I am disappointed by this because Doom 3 originally shipped with Linux support. At this time, Steam still does not support Linux, and I have no idea if id Software plans to support Linux with this updated version because they have joined forces with the Bethesda empire. All of the marketing and politics is disappointing overall, but the game itself is so much more fun with the Tech5 updates to the engine. The UI is a lot smoother. The PDA is actually working the way it was intended to 8 years ago -- if you stop walking around to read an e-mail, you will still be vulnerable to monsters. I love this series.
