Yeah I have never had an issue with first person perspectives and even prefer it for games like say Cyberpunk 2077 or Metroid Prime where is adds to the immersion and places you in the character's shoes.

Third person is fine too of course, I don't really have a preference, just whichever one best suits the game's needs and the developer's vision.

While grinding can be just a way to artificially make game longer, often it lets you adjust difficulty, giving you the choice of how much you want to level up and upgrade gear. At best it can even be alternative game mechanic to advance; for example you can have doors that you can either find a key to or get a spell (at certain level) to open. So in that sense I think grinding can be good game design.

And games inevitably have repetition. When the gameplay is simple but great, it effectively becomes grinding, but that's not a problem.

Psychologically broken & fatally flawed characters.
Cinematics.
Open world gameplay.
Long games.

Regular controls in VR. VR is already very niche and there are loud gatekeepers insisting that every VR game must have VR controls, everything interactive with your hands. I prefer more traditional controls than grabbing thin air. I can't enjoy No Man's Sky on PSVR2 with its VR controls.
