Personally, I don't mind constructive criticism. The only posts that get annoying are the "this game suxors" kind. If the game is that bad, beyond redemption, then you shouldn't waste your breath on it. Or bother the people who disagree. As for the more mundane criticism, well that's fine. That's healthy -- it breathes life into a game community. I think everybody who's ever made a mod has had some small gripe, some different vision -- why else make a mod? And I don't think you'll have anybody who thinks mods are a problem. Well, probably not. But you never know. Especially on a message board
Hmmm... as for the fresh air thing, I find the game evolutionary rather than revolutionary. It's like next years model of car. Shinier, slightly different, new, more mph, or fps,... you get the same kind of arguements about cars too when you think about it. The which is better / worse, it's a step forward / backward thing.
