Just wanna add here that I fucking love Stardock. Not just for their games, but also their customer service.
The whole Stardock Central thing really works, and I love how you can buy the box, but still download now and get playing while they'll mail out the dvd. Great thing is too, if I ever lose my GalCiv2 cds, I can just have it reinstall that game for me, expansions and all.
SoaSE is totally worth buying. Finally, I've got something for those evenings after work when I'm just a bit too tired to drum on Rock Band
