Each sizeable mod should just have its own subforum imo.
I'd have to vote no. Saw what it did to the Freelancer community, where only the big boys, who'd gotten in early, had their own sub-forums, and got a much greater share of site traffic, and all new projects starved. It wasn't good for their community, and I think it'd be really awful for ours.
First, we'd have a big, stupid fight about the definition of "sizable mods". Sizable how? Historically important? Popularity? Whether the creators are good at politicking? That's just a recipe for failure and an entrenched elite, and it's already bad enough here, given the skillsets you need, and the time investment you need to make, to get things done.
Secondly, after the big, stupid fight, we'd see multiple smaller stupid fights later on, when (hopefully!) new game designers, with cool ideas and plenty of energy and vim, come in, make really awesome games, get an audience and... "ooh, we're sorry Mr. Pwn, we love ya, but we decided, awhile ago, that the Big Eight were the only people who could have sub-forums. We quit adding them awhile ago, sorry...". How would that be, for anybody who's pushing it? Again, been there, and it wasn't good. I was the sole newcomer to have an exception made, in that community, and that wasn't good, either. It probably really hurt some people's feelings, frankly.
Thirdly, it's just silly. If a game is ever popular enough to support its own forum audience, then by golly, the designer / team can get their own forum for that. You can be as stupid as a drunken chipmunk these days, and set up a PHPBB (
I've managed to do it, even with add-on mods, and we all know I can't be trusted with sharp objects or really nasty code).
In short, it's elitist and would cause even stupider ego-clashes around here, it's bad for innovation by stifling newcomers, as if that wasn't already a giant problem, it's bad for growth, it's bad for politics, and it's bad for our customers, the players, in my opinion.
I would not at all vote against, say, a forum for game designers to primarily converse with each other about technical issues and practical problems, just like the art forum, which has (remarkably, and probably because I was a major dick about it, early on) not turned into a "lemme show you my latest fanfic drawing of a cat" forum, but mainly stays on topic about making functional stuff for Spring, and allowing un-released mods a welcome place to show off their stuff.
That might be constructive, by splitting customer-service issues from self-help. Anything dividing it further would be a move in a bad direction, I think.
