Although I've only seen screenshots in Next Gen, they look a helluva lot like CS pics to me. Perhaps I'm being too judgmental, though. But, that's just one guy's opinion. I never played the Quake mod either, but from what I hear, it's a pretty faithful translation. Nonetheless, TF2 is going to reeeeally play up the teamwork-strategy type deal, and since that's what will make or break it, I'm sure Valve will have it elevated to an art form.
Teamwork is fun when everyone's pulling together.
Even in TFC I rarely see that. Go on offense while I stay here. TF2 is so highly anticipated, i don't think that there is anything that i won't like. Go buy all their albums after you finish with the mailbag. And I think the new classes are cool, too, especially the Commander class.
