The science sucks in this game. In the universe star systems tend to be heliocentric ( with the exception of binary and trinary star systems). Take for example our own star system. You have the Sun in the middle with several satellite planets in orbit around the Sun. Masters of Orion 2 did just that. It had many star system that were heliocentric.
Speaking of our own star systems. TEC = human yes? Where is Earth, Mars, Saturn??? When I played my first game, I thought to myself, "I’ll play TEC and the first chance I get I’ll colonize Mars." Boy was I surprised.
Sins will be a hit. So if Ironclad/Stardock comes out with Sins 2 ( and there will be a Sins 2 ) make sure you get it right next time around.
