A writing sub-section within the RP section sounds like a good idea, I like it. Regarding a general games section, we already have a forum dedicated to all other games. A Games in General section would just be redundant since you can already talk about whatever video game you want in the Video Games forums. As for forum games, most of them serve no real purpose but to increase post counts in a humorous manner (such as count to x, or post a lie about whatever), so they don't really need their own section. The "acceptable" forum games are already being conducted in the General Chat already (though they're not limited to just those).
Well then, I think I've addessed everything. ^^
