At the very least it kept shitposting, racism, sexism, and low effort shit under control compared to places like GameSpot, GameFAQs, and Reddit. Too be honest I don't really know that many gaming forums.
Posting in OTs and the Retrogaming threads was great. Great communities sprung up around them. Off Topic could really get nuts with people like Lime posting for sure, but that wasn't what I was there for.
