What's a "flotilla?"
Lukeff, I expected it was an easy mod, OTOH some (most? The huge majority?) of people won't mod the game. The "abandon career" thing is really nonintuitive for anyone who speaks english since it is plainly stating that you'll never play that character/career again. Seems like that should get patched in, IMO (for those who won't mod, but might DL an official patch).
I understand the localization issues are pretty difficult, but my take is this: if it's a u-boat game, the thing should be spot on in German, and as good as it can be in other languages, even if it's not so great in english (I can live with that, or dust off my german (or ask my wife who is fluent, lol)). If it's a USN submarine game, it should be spot-on in American english, and as good as possible in other languages---and if that makes it so-so in other languages, that's fine (as long as it's playable). If there was a japanese version (playable IJN subs), then I'd expect the language to be as good as is possible in japanese, and if other languages suffer, so be it.
