I think that we should have a suggestion board in the Game 4 section. That way we could have regular topics in the pre-release chatter and separate suggestions from the discussion of lore and gameplay mechanics instead of looking for suggestion topics. (Unless pre-release chatter is a suggestion board since CW3 has Upcoming Release Chatter, which would make this post a waste of time.)
Judging by various Virgil's posts, I think it's bit late for that, as game's rules are quite finished and all that's left is a bit of balancing issues and story. I guess balancing will be a thing to discuss, but only after we get into the game.
