I really did not like it in GalCiv2.
It completely killed any interest I might have had at 'getting into' the universe, so I really don't care about the Drengin or Yor or whoever the races were, they were all just 3d models to be manipulated/squished underfoot.
Similarly I'd just stop reading the tech info, as it was invariably a mildly funny-to-unfunny quip about the technology.
Agreed, I started skipping reading it after a bit, though it wasn't really an issue, just not something I found which helped me want to go for deeper immersion. I'm not that worried about it, I prefer to have the required information, and anything else I can ignore or enjoy as it suits my tastes.
On a side note, has anyone played Kingdom: Elemental? Now that's a game with a sense of humor, though it's not exactly designed to be particularly serious in the first place...
