A couple of friends have the same issue with games. Never had it myself, I rather like the incredible pace of fighters in the capital ship video. I guess it is the fact you can turn around the Z axis as much as you want that makes most people feeling dizzy on that kind of games, just the same way actual real fighters pilots have to get used to be able to see the world upside down while racing at incredible speeds. It is something you can get used to I think, starting slowly and increasing the pace little by little.
