Other Things that can be added into the Skirmish Game Mode(Single and Multiplayer)

Map Size Selection

Map Size in AoE3 in both Original and DE is dependant on how many Players are in it, a 8 Player Texas will be bigger than a 2 Player Large Texas, while there might be some problem with the map seed creation and sometimes AI, Playing a 2 Player game with a 4-6 Player Size map should good for some casual players.

Personally I always have a 4 Player FFA since the map size is to my liking, 2 player maps is just too small.

200+ Population Cap

Note: there will not be any Ranked game allowed in a more than 200 population cap, so this is mostly for casual play.

There could be a new Population Cap of 300, 400, and 500, however houses will stay at 20 Build Limit, so no Japanese Players can build 50 Shrines in a 500 Population Cap game, but instead all Civilization will have a Hovels instead that can be infinitely built, but only provide 5 Population each while costing the same as houses, and any card that increased population space will not affect the hovel.

The Reason why hovels are infinite is to give AoE3 a real base building aspect, and making a really big colonial cities, and being less cost effective means that a player need to at least think about it, since turning 200 Wood for 10 Population is a big investment, unless you have a bustling economy and have space.
