This may seem like an easy question to answer at first, but, at least for me, it's a difficult one. It's the same thing as for films and books. I'm the kind of person who really enjoys to revisit media I have already consumed before. It's like "I know this is good, so why not try it again?" Also, it's not rare for me to get reluctant to consume a new game and books, specially when I know they are one of those in which I'll have to dedicate many hours in a span of weeks or months to finish it. Do you have an opinion about this?

Edit: And what about other types of media like films and books? It would be nice to see if your opinions regarding games are the same for these other too

Edit 2: To make things clearer, I changed "playing only new games" for "playing only games you have never played"

There are about a hundred worthy games at least I've never even done a second playthrough of because I want to play new to me games.
It would suck to lose it on new to me games, sure. But considering I could replay so many that I might've never replayed, that's worth it.
There are tons of open-ended games or multiplayer games I can't afford to lose playing.

Games that I already played, and about new games, I will watch some streamers that I like playing the game.

I already mostly replay stuff. I’m an 80s kid, that was the norm.

New games all the way, replaying something I have already experienced can be fun, but it can never match the excitement of discovering something for the first time.

Novelty just gives more dopamine.

I mean ive been playing games for over 30years, thats a ton of time and a gigantic library. Ill stick to games ive played already.  Plus newer games never feel as satisfying as my all time favs.

Good Lord, this is an easy one for me. Almost all future games will be made with AI. Some of them will be made almost entirely by it. Originality is at an all time low, innovation as well. Give me NES-360 gens and all its games any day of the week, a million times over. I don't want any part of where gaming is headed.

Yes, but nostalgia provides dopamine and serotonin/oxytocin, which literally eases mental pain and suffering.

I do enjoy nostalgia, but the pleasure of experiencing something new for the first time is just stronger for me, like how a freshly cooked meal always tastes better than reheated leftovers.

Well, you're young, so I guess that makes sense. Twenty years from now, however... lol.
