This is a map preset where you'll never miss out on wood. This rms will create a greek or norse map or something in between that's fully land (may have a center tho).
The map is entirely covered with lots of trees and many little forests. Since it's a light forest units and titans will NOT get stuck! There's enough space to build small buildings like storehouses and towers but beyond the town center patches you'll have to chop down some trees before you can expand with bigger buildings.
Notice: If you prefer to wall yourself in it might be a bit annoying to place the walls (since this is AoM we all know how much enemies love to glitch through walls if there are trees nearby) and often you won't have space to build fortresses until you removed a few trees there.
So even tho it seems very closed at first it's still an open map for everyone who likes to fight quickly (and everyone who doesn't wanna worry about having enough wood) ;)
