Unless your idea of fun is motion sickness.

This is very much not my experience

In a modern title designed to be played at 60+, definitely. I've been having a blast in dark souls 1 and GTA:SA recently, both of which are capped at 30. Older games are made to work at that FPS, and it takes remarkably little time to adjust and have it feel normal. If I tried to play armored core at 30fps, on the other hand, I think I'd rip my teeth out in frustration.

Edit: misinterpreted the comment above as "unless it's VR (i.e., in all cases except VR), you are not having fun" rather than "unless it's VR, in which case you are not having fun."
