The first several hours after purchasing my VF2 game my motion sickness (as i call it) was so severe that i was going ask for a refund and get rid of the game. I couldn't play for more than a few minutes and the nausea and dizziness got to be unbearable.
But it seems to have improved the last few days as long as i move my peeps very slowly and not jump around in the game much.
Moving the screen or peeps slowly is a good idea. Even so, this game is less busy and does not demand a lot of repeated or rapid mouse or screen movement.. or repeated clicking.
Not constantly looking at the screen and keeping game play sessions shorter helps. The slower progress and option to pause the game means there is no reason to be in a hurry.
And then...with Meniere's..some days are better than others :-)
