I don't like the german titles, because they always have to change them...
The Gunslinger - Schwarz (Black)
The Drawing of the Three - Drei (Three)
The Waste Lands - Tot. (Dead)
Wizard and Glass - Glas (Glass)
The Wolves of the Calla - Wolfsmond (well...Moon of the Wolves or so...)
Song of Susannah - Susannah
The Dark Tower - Der Turm (The Tower)
They didn't change any names, so Roland is Roland and Oy is Oy.
Gunslinger = Revolvermann
The Crimson King = Der scharlachrote Koenig
Big coffin hunters = Die großen Sargjaeger
Beam = Balken
Perhaps I get the english version some day ^^
