Generalizing the codex from a brief peek at it, is not going to give you a good idea of the place. I've been there since 2004, and years ago as others have mentioned it was a very good place to discuss cRPG's completely and openly with no moderation (which of course allows the morans to run free). The last few years the forums are now flooded with spam posting and image spammers, but a few good and quality posters do still come around now and then. Thankfully most of the morans who run around do eventually get tired and leave, but then another new one comes to take their place. You do have to look hard to find good solid discussions, but they are there. The codex of late is basically a pile of elephant dung, but if you sift through that a little bit, you will eventually find a diamond. Codex Workshop forum is usually less spammed and can on occasion have some very good and in depth discussions there. And seeing peoples join dates can easily help you spot the terrible crap posters, and just ignore them and continue on. Just stay the hell away from General Discussions..... you have been warned.
