Hey Ovi! Glad to see you!
Yeah I agree on the game needing to be long-term. That was my original intent with PCP4 (or 3?), which is why we made that forum. I'd get that team back together if I knew how to contact them all, but I don't. But yeah, check the cartography topic and look for any threads named Dawn of Worlds (DoW) or Planetary Construction Project (PCP). We did three or four editions of each game, so there's a ton of content out there already for us.
However I also have no problem starting from scratch. Though I'd need to get my Photoshop situation resolved.
