Weeeell... allow me to throw in my voice as well.
I bought GalCiv, GalCiv II, and all expansions. I really, really approve of the free updates I could get, which improved the game even more (and I'm sure you'll agree with me on my high opinion of this game).
Now they've decided to switch to a new updating system. I don't know why, and - quite frankly - I don't care. It means I have to reinstall a fair amount, but since I do have a 16MB/s DSL (braaaag bragbragbrag), I don't mind much.
My thoughts are: compare this to other games. You buy them, maybe you can download a fix for some of the major bugs, finished. You paid a large sum of money, gort a (possibly DRM'ed) game, you play it, done.
Over here, the game keeps getting imroved for free after I've bought it. If I need to install some weirdo program which does not spy on me, I am willing to do this.
Anybody with update problems should call customer support, they're fast and friendly (first hand experience).
PS: Sheeeesh, am I looking forward to the new MoM-type game!
