I’ve heard you guys briefly mention Dungeon World a few times and I gather neither of you is a big fan. I’m sure you’ve mentioned why, but I don’t recall you ever dwelling on it too much. I’d be interested to hear a discussion about the game and PBTA games in general.
My own take, fwiw: I really like the rules-light feel of it and the way the player-facing roles tend to speed up combat. I think the list of basic moves pretty much covers everything the players might want to do. The only one that gets a little clunky for me is “discern realities.” I prefer to treat that more like a traditional perception check because I have found that the players sometimes have specific things they are looking for and asking a general question doesn’t seem to fit the situation.
I also own Zombie World and Masks: A New Generation. I got to play Zombie World at a convention and thought the card mechanic was refreshingly fun. Unfortunately, I have only had one brief opportunity to run it. As for Masks, I really don’t like it. It seems like they just added to much to the core PBTA mechanics and it left me feeling uninspired.
