lol, SC2 is cake mix compared to BW. In BW you couldn't just gather all protoss units in 1 group and a move. You could only group 12 units in a group. Control was actually incredibly difficult. Also when casting spells, you couldn't just select all your casters and cast, or else they would all cast, had to select one by one. Also could not put buildings in control groups, each worker had to be manually put on minerals when made, just everything is so much more difficult.
