A few people at my school organized a RTS tournament, with Starcraft: Broodwars, Warcraft III, Age of Empires II, and possibly a Red Alert game (pending more copies of the game). The SC games will be 1vs1 on a random 2 or 4 person map. I used to be decent at melee games, but I started only playing UMS maps, and my "skills" went away..plus I haven't played in 6 months. So, if anyone has the time, could you please teach me some good tactics for SC? I'd like to win this section of the tournament.
