This is a quick question to all you SC freaks out there. I have always been fasinated by the "rock-paper-scissors" of SC (particularly SC1) and how that balance played into the full game melees. For example, in the full game "Beginner's Luck" a single Syreen is pitted against 2 Androsynths. The 'Synths have a colony and a space station and the Syreen's job is to kill the station. The game is playable on either side. If you're playing the Syreen, just hit the colony quickly, pump up you're crew and they 'Synth's pose little problem. If the 'Synth's sit on thier colony and wait for the Syreen, the first battle could go either way and will usually determine the end of the game.
It's that balance that intrests me. If you've ever played a human in a 'Synth vs Syreen battle, you know it'll be a close one, either way.
How many other balanced match-ups can you guys think of?
