I'm glad I'm not doing translation. There's a lot of it. For a strategy game, GalCiv has a lot of text. GalCiv II may have more text in it than most RPGs. This really stems from the decision to be a single player game. By focusing on the single player game, we can sit down and put in per-race dialog on a per situation basis. Most people won't see a fraction of it. Play as the Torians and you'll get a different set of dialog and reactions than if you played as a human or a Drengin.
The tool we made is really pretty neat. I can type in a # and type in alternative text. When the parser sees a # it knows that there's another randomly available bit of dialog to select or in other cases another bit of text based on a slightly different situation.
I don't know how many people even care about that kind of thing. Strategy games usually have a pretty narrow set of text. Part of that is to ease translation and part of it is the consensus that it adds little or at least not enough to justify the effort. But for me, I enjoy seeing players that say a lot of different things. And plus, I type 120wpm so it's not a big deal to type a 10x10 grid. We also have a "generic" category so that if it can't find what it needs specifically, we can wimp out and just fill in the generic stuff.
