Starcraft RPG?

I'll get to that in a sec. I had an okay day today. Two quizes. English paper due tomorrow. Arty and I (Arty's someone from D&D club) have decided to create a new RPG, based off of Starcraft. d20 system, but that's about all the similarities as in D&D. Today was good in D&D club. I DMed for the first time at club, sent them off to kill someone who was crossbreeding monsters. They fought a fire-breathing monstrous spider (Dragon + Monstrous Spider) and a "Magma Elemental" as Arty called it (Fire + Earth elementals). Good stuff.
