Would be nice to be able for two or more players to play on the same map with same races except for the humans race custom or not.Players could challenge each other for highest points,fastest victory based on year in all categories of victories.
Smaller groups from each league could share the map and swap strategies and tactics,although I suppose this could all be done in PBEM mode.Medals could be rewarded based on these as well.So one player would create a map and be able to put it in the library as a challenge with play parameters etc.
