I got a DK2 when it first came out. When I tried a rollercoaster, I felt a little off but ok. Over the next few weeks I noticed slight nausea with the Zelda demo, Tuscany, and the Tiki boat. But that was nothing until I tried Quake 2. After fifteen minutes of playing, I couldn't stand up, and was extremely ill for several hours. Since then anything where I am not seated triggers the same feeling again.
I think the brain/balance issue is very common if not the norm; much more than is accepted in the community. It will be a disaster if it's not solved before a commercial release.
