Depends on the genre - when talking about western RPG, that would be Dragon Age Origins; japanese rpgs - Shin Megami Tensei Digital Devil Saga. Horror games - Silent Hill 2 and Forbidden Siren 2; Action games - Metal gear Solid series.

Deep stories and good world building is a must! Pacing is also very important when talking about general enjoyment I get from playing a game; bad pacing can ruin the whole experience. I like when enemy types, locations, story threads and game mechanics get introduced slowly, bit by bit.
I also dislike open world games; cant think of any open world game that wouldnt benefit from some streamlining, or even completely linear approach.
Graphics seldom matter, but I vastly prefer games with really tight visual design and art direction. Game can be early ps1 level of low poly, 32 bit, text based, I dont care, as long as it has some artistic integrity, nice menus, pleasing color palette, and overall effort put into it.

Wizardry Online. I loved the atmosphere, and the fact that its so hard, it basicly forces people to form groups in order to survive.

Super Mario. I was around 2, and I remember being scared shitless of playing. The thought of killing little red guy by accident was horrifying. So I kinda watched my father play the game for a month or two, before trying to play myself.

Yup. I play lot of bara visual novels/ gay dating sims/ , etc, and theyre pretty much made for wanking purposes. As for mainstream gaming, I fondly remember faping to modded version of Dragon Age Origins.

Persona 5, back on its release day. Ive been playing it since, first by myself, that took 140 hours to complete, then with my friend. Would recommend to anyone whos fan of jrpgs, and doesnt mind anime aesthetics.
Oh, and I bought Abzu for my mom few months back. She likes pretty things, colorful fishes and diving, so. Theres that. It was on sale on psn.
