There are some great maps of Yugoslavia or its constituent republics out there. While some may be more aesthetically pleasing, this is an outstanding map that ranks right up there with any of them in terms of gameplay.
Like most political maps, this lacks the chokepoints that terrain features provide. This is more than made up for by the non-standard shapes of the territories, the varied bonus sizes and the hefty superbonuses. It's not so much about blocking the enemy, it's about what you allow him to take.
