I hated achievements when they came into place, however over the course of time, achievements showcases progression and can show you and others that you finished the game.
I finished Mario Odyessey and Zelda BOTW, how can i prove this? I cannot unless they see my hours spent ingame and my lucky photos i took of me fighting the end boss etc.

Having achievements even just basic achievements like completing levels etc would be welcomed. They dont need to go full hardcore like in the Gears games where you need to play 1000 matches etc.

Meh.

Lots of Nintendo games have in-game achievements already.

I don't really care one way or the other about achievements. They're about as rewarding and fulfilling as getting a postcard. (Don't think about it. Don't think about it. Don't think about it!...

...ARGH, I THOUGHT ABOUT IT!)

Of course I can play games just for the experience, but once I have ran that well dry, having some challanges to collect is always a nice reason for me to keep playing. When I am faced with the option of continuing to play a game on Switch, past its play for fun point, or playing something on PS4, PS Vita, or Xbox also past the point of, just for fun, having Trophies/Achievements gives me something to work for. Being able to do something I enjoy, while earning a Trophy/Achievement, and some cash while doing it is a win-win in my book. 

That said, Trophies/Achievements arn't for everyone. If they don't matter to you, then your not missing anything. 

Okay thanks, I can get behind that; after you’re done with everything you wanted to do, you use the remaining trophies as a sort of expert challenges.

Makes sense, I could see the fun in that.

I couldn't care less about achievements. They just get in my way. They take me back to reality when I'm immersed in the game. I always turn em off. Also, I don't need to prove myself in front of other people, specially about something as mundane as a videogame.

Finally... doing something not because the game suggests you or tell you to do it within its world and rules, but because the developers directly tell you seems very dumb to me. But to each their own...

About time, I will always pick a game with achievements over one without. Probably one of the main reasons I only pick up my switch every couple of weeks, despite having every single 1st party game released so far on it. Even though i don't chase achievements anymore, I just like having them there as a way to show my progress in every game iv played.

Yeah same, i love looking over my list of around 700+ games I've gotten a trophy on and seeing my progress. It also motivates me to go back to certain games aswell and play them again. 

Makes no difference to me whatsoever. For me, it's Achievements in every game or I don't care. Just one game=a leaderboard.
It's the reason why I didn't care about trophies on PlayStation 3. I'd played so many games before trophies that the late addition of them just didn't feel like like a priority to me.
