Sorry but who here has Ever gotten seasick whilest playing a game?

Especially when the bobbing is
only present when a sprint button is pressed and is only there for a certain amount of time AND you can stop any time but releasing sprint (incentive to not sprint everywhere so much?)
Plenty of games have head bob and I've never experianced being Seasick whilest sat on a PC I'm sure plenty of others will agree that Doom wasn't ruined for them by having to reach for a bucket every time... If you do then perhaps move your head a lil further away from the screen, Maybe look away every now 'n then?
Maybe you should feel dizzy after running for long periods, Simulates losing breath and feeling light headed and such.

That's immersive.
imho I think if you start feeling motion sick from playing too long then you need a break
I don't think "some" people feeling motion sick whilest playing is good enough reason not to include a very very widely used and realistic effect that has an effect on the way the game is played and strategies used
