Agreed, I like MoO3, but until they get the patch out, I'm primarly focused on GalCiv. Once MoO3 plays better, then I'll see which I play more, though I can't see me entirely giving up one or the other, they satisfy different cravings/needs. GalCiv is always a fast-paced game. MoO3 starts to drag quite a bit on my decent but dated gamemachine (AMD 1500, 512MB DDR, GF3 Ti200) after a while, but GalCiv zips along. On the other hand, there's a lot more decisions to be made in MoO3.
I think the "one-more-turn" urge is as strong for me in GalCiv as it is in MoO3, but on the other hand, since I'm always in the middle of something with MoO3, I hate to break for any reason. With GalCiv, I don't mind taking breaks to pay attention to the family because I can always come back to the game, and with just a minute or two of looking at the situation, remember right where I left off.
