I also speak german, since I live here, and I must say, yeah, the names were silly, but I kind of liked it. It put a certain quench of extra humor into the books and I don`t see why it shouldn`t work. To be honest, reading some peoples rosters I think the books had the better names

I fully agree on some of the mentioned starplayernames. Wasn`t "Hack `n Slash" a name proposed by the community? No difference to Dunkel Hoffnung, which translates to "Dark Hope" in english and fits into the theme of him saving his family from a demonic curse.
Haha....gotta say, I laughed pretty loud when I read the players name from the Chaos All-Star: a big ratheaded player by the name of Mackey Mouse.
In my eyes "Rumble in the jungle" was the weakest of all five novels. I`m suprised, but I agree with Darkson on that on - Blood Bowl works quite well as a graphic novel. The visualization also brought some extra humor, like the big chaos sign on the explosion, when their dug-out blows up.
