Big fan of Sci-Fi & Space Sim MMO's. I remember the days of Wing Commander (so yes aging myself here) and very impressed with the work put into Chris Roberts dreams!!
Space/Sci-Fi MMO's played in the past:
Star Wars Galaxies -- 3 years
Eve Online -- 8 years
Star Wars: KOTOR -- 2 years (got bored quickly)
Star Trek Online -- Less than a year
I'm a computer programmer by trade so yeah. If I am not in the outdoors hiking then I'm hanging around within these type of games.
Roles in SC -- Exploration, Trade, Light Combat and possibly Mining/Industry/Salvage.
