Well I found a few ~1700 rated replays. A couple of drops to the far corner, some air play, but not really very interesting games to watch.
Players are forced to leave the starting base after 2-3 factories due to lack of reclaim/mass and there are only really two spots worth going to; failure to get one expansion is almost always game-losing despite so many mexes around the map.
The 8 middle mexes are potentially useful but easy to raid and to spread out to fortify.
Even the corner mexes are far enough apart that tanks sent to the middle of the clump are out of range.
My thoughts on a better version:
- make it a bit smaller, e.g. 15x15
- mexes in expansions should be a bit closer together to make defence with a PD easier
- add some mass reclaim
- maybe reduce the mex count slightly
Ultimately I don't think maps with four-fold symmetry are great for 1v1 or 2v2, personally. Some asymmetry makes choices about where to send the ACU meaningful instead of just 50% chance of meeting the opponent.
