1. What published RPG do you wish you were playing right now?
I've got a long list of RPGs that I've purchased (and love) that I haven't yet been able to convince a group to play. That includes plenty of games that were a "hard no" for my players and a large assortment of games that we simply haven't made the time in our schedule yet.
I guess if I had to pick one game that particularly tickles my fancy, though, I'd say it would be Ken Hite's Magnum Opus THE DRACULA DOSSIER. A sprawling, open-ended spy thriller where you hunt the King of the Vampires across three eras, with the greatest RPG handout/prop of all time -- DRACULA UNREDACTED, a draft of Stoker's novel with marginal notes from three generations of British intelligence officers(!!!) -- that's totally my jam. I would rock on that as a player or as a GM, no question.
2. What is an RPG you would like to see published?
Selfishly, MINE. I would love to get my game LOST PINES in shape and see it in book (and card) form, but that's probably not going to happen any time soon. I may release it here as a free thing that people can play if they want, using my crude playtest materials.
Realistically? Hmm, I'm not sure. I guess I'm not that interested in seeing yet another licensed game of some media property, which is probably the typical answer to this kind of question. Those often seem to fade very quickly, even when they're excellent (like the exquisite SMALLVILLE and MARVEL HEROIC ROLEPLAYING).
I would like to see more roleplaying games that aim for the kind of play that we see at my table and enjoy the most, which is to say dramatic play. We have gotten a lot of mileage out of things like PRIMETIME ADVENTURES and DRAMASYSTEM over the years, so I guess I'm most looking for the next thing that's going to give us new tools to approach the game as we play it.
I suspect that the answer may be to read and play more LARPs. But that's a discussion for another day.
