Storm's Keep by Qancakes
If you have been so tired of the popularity system or multiplayer maps, try this single player campaign by Qancakes. You are a ghost send to a distant zerg infested planet to investigate the problems. Even though the maps is quite easy, you still have 45 minutes of a good story and nice terrain. Download the map on mapster or find it on battlenet EU.
Haha, you caught my attention with the "tired of popularity system" introduction. We could use more singleplayer capable maps...
