I have played StarCraft 2. I chose an older era marine because 1. I like the story of the first StarCraft more than StarCraft 2, and 2. because I like the original design of the Marine armor. Also because the UED are cool. The time period he's from is the time between StarCraft 1 and 2.

I do like the idea of separate ships from separate universes crashing, and everyone being forced to cobble together some sort of abomination of a ship from the wrecks. Will there be NPC's onboard the ships that the players will control? I'm thinking of it being set up so that each player has a group of NPC's they order around, basically making each player their own little faction.
