Looking at the games section of the forums, at least 75% of the topics are "(this) or (that)?". Implementing polling capabilities would both streamline all of these topics as well as allow members to view the opinions of others... so maybe that's something to think about.
As well, in the games section, there are HUGE amounts of repeat topics that, in my opinion, get kind of annoying to see. Adding opic merging and/or forum moderation features may reduce the amount these appear. You know, if you want to add some more structure to the forums.
These forums do need more features, desperately. HOwever it is unlikely anything will be changed for this version of the site, because a new version, Armor Games 3 (AG3) is inn development. It will have many more features for the site and forums.
