Sam, this is amazing. I can't believe how quickly you're progressing!
My $0.2 regarding swearing; damn is fine by me, and in fact, I don't mind any swearing whatsoever as long as it's in context. If you look at anime, and even some sampled speech in Japanese games (like Bangai-o) it's a fact of the matter that the Japanese seem far more relaxed about it.
If we can take for example, a charachter is ambushed in a firefight and his friends and comrades are dying around him, I would fully expect him to swear as much as he likes.
Aside from that, sterling work, and I'd like to add my vote for City Hunter for translation.
