uhhh theres a difference between PLAYABLE and FINISHED....

if it runs but has only place holder textures, then it is playable, just not finished..:P

The grayboxed maps, at least eclipse, is actually more playable than for instance docking, refinery and mineshaft. Don't be so quick to judge, you might miss out on some excellent maps.
