Again, no offence meant, but there's no way Doom 3 will better HL2 in the important areas
Complete silliness. You have no idea in what ways one game will be better than the other. You can speculate all day long, but you don't know. id's single-player experiences in the past haven't been great, but that doesn't prove anything regarding Doom3. Maybe they got it 'right' this time, maybe they've made truly revolutionary leaps in atmospheric storytelling that will change the industry. You won't know until you've played the game, and until you've played the game, you're talking out of your ass just like the guy you replied to.
Until you play the games, you don't know. End of debate.
