Allrighty then, thx for the replies everyone.
I guess my fear being a warrior was a bit exaggerated
I think i'll go with a warrior that specialises in dual wielding like i usually do and then invest in some mage skills later on. I just have to be carefull of everything that move's in the beginning just like in risen or the gothic games in general.

One more thing however:
How many hours approx. will it take to fully complete the game. I mean doing all the side quests and stuff. That is at least if they are interesting hower and not like some of bioware's mass effect 1 & dragon age's quests
