I have not played an actual game of it against another person, so I can't really speak to how it plays. (Playing against myself in two browser windows doesn't count.) I wonder how often I will forget to draw a City card when I'm supposed to IRL, isotropic of course does it automatically but it seems easy to forget. Maybe it will become natural once I've actually played it a couple of times.
Implementing it was, like, 2% of the effort needed for Figures, so that was nice.
Chris (of Asmadi) wants to do an "open beta"-type thing on isotropic and get data on how it plays, so it's likely you'll be seeing it soon.
