I recently bought Mirrors Edge, and started to play it one Friday after work.
I also became quite ill and very irritable, I initially blamed it on the barbeque meat I had eaten earlier that day, but noted that the more I played the more nauseous I became. I eventually developed such a negative attitude towards the game, just the sight of the disk would cause a nauseous reminder. Weeks later my Girlfriend came over and wanted to check the game out, so I played a stage or two. After about 20mins she told me that she felt ill and wanted to puke and subsequently went home. I continued to play for about an hour until I also once again became ill with the same symptoms. Its actually such a quality game, but I just cant play it..…. Such a Pitty.

Cheers,
Simon.
