If you want the strategy you should go for GalCiv2, it's turn based, so you have time to think about everything. With Sins being real time, it can't have as much depth as GalCiv2, we just wouldn't have time to manage it all. I've only played Sins briefly so far so I don't know it in great detail but unless you want a change from turn based games, then I think GalCiv2 is the one you want to try.

You'll want to go to http://www.impulsedriven.net/ to seek support for that. Stardock sold Impulse to Gamestop earlier in the year.
