Since GC is not and probably wont become a Multiplayer game in terms of PBEM capabilities directly I was wondering if some sort of Race Editor could be created after the game is released.
Here we could have more sayso in what each race says and does etc along with the order.
Maybe a Human Race could be created and used multiple times in the editor so a PBEM could be created without password protection.
The basic thought comes from ACEdit 2.0 which is used in Sid Meyer's Alpha Centuri.
