It's universally accepted that HL2 is far better then Doom3, you are utterly alone in your opinon
I don't think I am.
I think most just say HL2 is better because
a) People like you just shout them down.
b) They like the mods and assume that because TF2/CSS/Portal is good then HL2 must be as well.
It's just such a bland game. Any idiot could take an Orwellian regime, throw in some random dude in a suit and tell us nothing about him, make it look pretty and chuck it on the shelves.
It's not a bad game. It just never raised the bar at all. The first was great because it did everything better than anything else at the time. The second does not.
Doom 3 has it beat in graphics, physics, atmosphere, immersive gameplay, and as an added advantage, doesn't come forced with Steam.
