Simulation games in general reached a whole other level with VR, just the added depth perception makes it impossible to go back to "flat" screens again. The degree of freedom to move your head to look around is underrated as well.

I dove into VR first with X-Plane 11 I think, which was janky at best, but nowadays Microsoft Flight Simulator has really good VR mode, and it's just such a great experience. Spaceflight simulators like Elite Dangerous are quite fun as well, but harder to relate to, so seems my brain doesn't get as fooled as more "real life sims".
