The ONLY thing that I really want to change about the game is the "Let's kick some ___" voice clip on the Marza. Is there an easy way to change it? I would even use one of the other Marza audio clips if it could work.
Why does that bother you? I think it's great. Just be glad that one of the ship voices doesn't say "F-Yeah" at some point (see Unreal Tournament 3).
If you're offended by vulgarity like the word arse, then you might be better suited for a game titled something like "Carebears and Friends" or "Bible stories" or some such. Also, I suggest never subscribing to cable television or going to anything other than G-rated movies. You can also find some very very naughty stuff on the Internet like, <gasp>, naked women and men and women touching each other in various ways, so you might want to reconsider your Internet subscription.
Stardock and Ironclad, please don't succumb to ninnies and make all of your games G-rated. What happens when someone complains about all the violence in these war games?
