Looks like I'm not the only one interested in trying to give 4e-esque monster abilities to humanoids in a gridless system-- the current D&D Next playtest is doing the same, at least for some monsters. I decided to download the latest playtest and see if what they've got is any more applicable than I already had. Some of 'em are pretty clever, but I think others need some work. I may have to do a second take on that post with some cues from this.
Also, I finally got a look at Carcosa and its psionics system is everything I wanted to do a couple months ago except better handled.
