Doom 3 of course. Didn't like Quake 3, so I probably won't like Quake 4. The original Quake is still the most fun to play of them all. Too bad the graphics are horribly outdated.

I am a Quake 3 player...
but the fact that raven is developing Quake 4 doesnt suit me...
The gameplay in Q3 is verry special... i can only hope it will be greatly mp focussed and that it has the good old quake gameplay!

I believe Q2 is still one of the best multiplayer games ever made (I didn't like Q3A until they did some point releases and changed the physics a bit) and I hope Q4 will not turn into some Unreal Tournament-like game but also have single player possibility

i agree with NecromanX... Raven better be damn carefull with our precious Q3

q3 gameplay = OSP
ID soft only has to provide a kickass engine and netcode imo :)

Doom 3 is better than quake 4.Quake 3 is really great and I love to play it.
They ruined quake 4 because it doesn't have a fast action multiplayer like quake 3.And quake 4 doesn't have bots.
