$100k per language subtitules? Really?
2. that's gross, not net. Subtract 5% for kickstarter, 3% for the credit cards, royalties for game shipments and reward costs, and you're probably looking at less than $50K
3. good professional translation costs ~$30K per man-month if you use an agency. I wouldn't be surprised if Shenmue contains more than a novel's worth of text.
I'd say that just put arbitrary numbers in there since the project will require much more than $2 mil. to complete.
You are right about points 1. and 3. though.
Granted this isn't the 16 or 32 bit era where all this typography stuff had to be rolled by hand, and probably looks like ass with a monospace font in anything other than japanese.
Translating a movie is one thing, it's only a few hours of dialog. Games often have way, way more.
