From my experience, this place is miles better than most gaming forums, if not most forums in general. Comments are thoughtful, well put together, and show a genuine desire to contribute to the discussion (although that's partly attributed to the occasionally overzealous moderation team). I hang around these forums for a half hour, then I go look at Rotten Tomatoes or something and the difference is astounding. And as an American, I also like that there's a decent sized international community, which isn't as common on some forums.
If I had to criticize it, I'd say it's too self victimizing and self important (the number of "nice guy" or "friend zone" threads I've seen are beyond counting), and on occasion, there can be a sense of male focus, if not outright sexism, though it's not nearly as bad as other gaming forums. Other than that, it's one of the most civil and approachable communities I've seen.
