I just discovered the Table of Contents feature and I think it'd be something useful to add to games that have their rules in the wiki. I've added it to Dueling Runes so you all can see how it looks.
Another possible change is to make the Comments for each game page hidden by default. What do you all think of that one? It makes the game page look cleaner, but at the same time offers no indication of how many comments (if any) are there on that page, which bothers me a bit. Anyway, it's also true that new comments for games also appear at the forums and at the recent posts page and RSS feed, so it might not make much difference in usability…
Thoughts?
