I'm thinking about buying the game, but when playing the demo I get motion sick. That's odd because almost no other game has ever caused this for me. Does anybody experiecen the same? Has anybody tried chaning the FOV?

thats never happened to me! you must get immersed in your games unlike anybody else!

Just in case anybody else gets into this situation. Changing the field of view did the trick for me. To my surprise it already was 90 while it looked like 80 to me.

However: to change the fov just open the console with tab and enter "fov 95" without the quotation marks. As soon as I changed that the game felt completely ok.
