The_Blog: In Germany we spell it like it is written. So not "day-us" but instead "Deus Ex". But you have to keep in mind that the "e" and the "u" in german sound different than in the english language. In the english language the "e" is more pronounced like our "i", while we pronounce "e" more like in the word "escape". I struggle to find a good example for the "u" in the english language right now.
Tarnicus: I studied German briefly in high school and can remember some pronunciation but very little vocabulary. I'll still never forget Max Hoebeck, who was of German ancestry telling me to respond to the teacher's question of "was ist das?" with "Das ist meine lange fleischiger schlange" :P
I learned a bit of German informally when I worked at Red Hat so I could chat with colleagues in the German office. Ok, it was more like goof off with my broken Yoda-German dialect so to speak. Ah, the good ole days. Sadly, I never learned to speak it or listen/comprehend it well, just read and write at a basic level. Some day I would like to properly learn German though just out of personal interest. I always found the language interesting sounding and unique. :)
