When starting my game, I choosed that because I was not sure to what to choose (now, I think I should have choose PerfectWorld, or map fully supported). Is there any issue with Mongoose map ? Or compatibility problems ? I would like choose 3 planets also, but as I was really not sure at all, I didnt. Is it playable with C2C ? Futures eras can work without it ? As all the map are named C2C_MapName, I was thinking all these maps was ok.
