Die Dunkle Dimension

Dunkle is a German Ultima IV clone, and unlike the author of most clones, the developer here did a good job retaining most of what makes Ultima IV so special, including the keyword-based dialogue system, the sense of exploring a large world, and the tactical combat screen. It lacks the virtue system, of course, and you control only one party member throughout the game. Still, it's a better clone than most and all in German.
