Great! I definitely need more feedback! Its actually a mod with a few maps released, but the maps are Blizzard's so I only seek feedback on what the mod changes.
Mod/Map names: SC Expanded. Search for 'expanded agria valley', 'expanded arakan citadel', 'expanded abyss' or 'expanded lost temple' depending on how many people are going to play it. I suggest Abyss, since this map has some triggers to fix the AI.
