Those 2 games are nothing alike at all. Dark Messiah is a first-person action RPG, although I use the term "RPG" lightly in this case. Arx Fatalis is more of an old fashioned dungeon romp, and offers a lot more in terms of actual role-playing.

Absolutely, one of the best games on that list, and a must-play for any crpg fan imo.
The other games on that list that stand out to me are Gothic 1 and Risen.
