But the twist is in unity, your issue might be with 3d games in general
I think I get what he's saying, since I also get nausea sometimes from certain 3D games, though not from Last Hope. A lot of indie 3D games just put every effect the devs know on full blast because that's what the big guys do, without understanding why these effects are added(and to be honest, sometimes the big devs don't really understand either).
Depth of field, lens flares, motion blur, bloom,

, low FOV(field of view) or badly implemented

, all of these effects can give people motion sickness/nausea. That's why it's usually best to go in the options menu and turn them off and make the FOV higher if there's an option for it. The problem is that a lot of developers don't bother separating them in the options and usually lump them all together into one single option called "post-processing" or "effects" or something like that. Kinda sucks if you like some of the effects but don't like the others.
Some people don't even realize that it's one of these effects that's giving them nausea and they never bother going into the options menu.
