Ok, I upvoted you for finding this, where can I downvote Uwe at?

Seriously, there HAS to be some kind of German tax law that we don't know about where if you fail horribly on a movie/game you get som ekind of money in return. There is no way that this guy would keep getting hired any other way.

None of the game developers wanted to sell Uwe Boll their movie rights, so he's being forced to make his own video game just so he can have a story for his next movie. Poor guy.

This game is already made into a movie.

Every movie and gaming website with ratings, I would say...

You've pretty much got it down, actually:
From his Wikipedia page:
"Boll is able to acquire funding thanks to German tax laws that reward investments in film. The law allows investors in German-owned films to write off 100% of their investment as a tax deduction; it also allows them to invest borrowed money and write off any fees associated with the loan. The investor is then only required to pay taxes on the profits made by the movie; if the movie loses money, the investor gets a tax writeoff."
