I used to love FFXI but I feel like out of all my nostalgia MMOs it’s aged the worst, even EQ has aged better.
As far as EQ, I’m not familiar with motion sickness but I know it has camera controls and different modes, I was thinking there was a hotkey or console command for raise and lower camera.
My other nostalgia MMOs were Rift and Ragnarok Online but I’m pretty sure both of them have gone to shit.
Oh, and EVE Online
