Map Loading
To save time, begin loading the map to be played at the Skirmish setup screen. Do not do so to the detriment of responsiveness in the setup screen, but as soon as a map is selected each system involved could be loading it up in the background - the asset is not affected by other player selections.
Perhaps the map only loads after a short period of time has gone by, so as to give players the chance to yay or nay the venue before the load process begins. Also, loading a map into memory shouldn`t need to be done only after players are sync`d up.
Not critical.
