Like you, i too get a sharp and painfull headache from being disorientated too much in all other first person shooters. it was the disorientation that had me on the floor wretching my guts out. since my first encounter with these type of games many years ago, i've tried to avoid them no matter if it was fun or not. mohaa has been the first fps game that i thoroughly enjoy and am not sick from. thanks 2015
