Quake 4 was alright. Mind you, I had to switch my brain off, and I was drunk for practically the entire thing, so it's not exactly as if I'm showering it in praise.
btw if you do get it running... it was crap! compared to quake2 ... I played it recently and the whole deal was crummy. quake 2 was more quake 2! quake 4 was just not what it could have been
