I think this was the first RTS game I played properly, outside of seeing my neighbors play Warcraft II. As a big sci-fi kid already this was just awesome. First unlocking the Zerg and Protoss campaigns after playing as Terran for what felt like so long was cool as hell. I usually ended up leaning on cheats for later levels since my ability to micromanage an army was crap, but I always had fun. The cutscenes and voice acting felt groundbreaking at the time as well
