A well done map, one of my favorites. Capitals are pretty huge, and a high risk, high reward situation. A few different ways to play the map, too. Only downside is the advantage to the one who goes first.
Probably ideal for epicly large games, though those tend to take months and people drop out. Good with fog, some tunnels are arbitrary. Not that great for 1v1, going first and starting placement tend to have a bigger effect on the outcome.
