And I mean that literally. I've never had problems with first person games, though I hear some people do. I think it's a problem with FoV (Field of View) for people that get sick playing them.
Yet as I sit here playing the campaign and getting my first ride in a Mantis, I feel utterly nauseated. There's a slight dizzy sensation, along with the strange feeling that I'm bouncing up and down where I sit, even though I'm not. Ever as I paused it to come type this, I'm still feeling it.
Has this happened to anyone else?

I'd suggest to stop playing for awhile. That's always a good move. Give yourself time to relax or something.
Some people just have sensitive perceptions. I mean I can't understand at all what TC is going through, but each manufacturer has health warnings that no one ever reads talking about stuff like this. It's probably not serious, but you should probably just chill for a while.
