I remember the GUI-less version that got leaked. Pretty fun to play around with though it had a lot of features that were unimplemented or purposefully broken. I fixed it up a bit, hosted my own and had my own taste of CityRPG drama. Not fun. Especially when my copy was leaked by a "friend." Now it sticks with me. I still get people who think I worked with Iban to create this mod. Jesus. Worst thing I ever did was open that damn zip.
Anyway, glad to hear a good, well run version is in development. Don't let it out of your sight. Oh, and I find the most fun systems are the ones that don't turn into city based DM's. If there's a way to keep the RP in CityRPG, do it.
