I recently earned the platinum for Riders Republic, its a fun game, takes around 40-45 hours to get the plat and outside of tricks battle mode its not too difficult, but I enjoy playing tricks battles.
I haven't moved on from the game after getting the plat though cause im levelling up to get elite level gear to win 64 player mass races, I got first place for the first time yesterday and consistently get podium finish

To me, they feel kind of OP to discover if you're not a very motivated person, but I suppose that's who they're for. I did one of those trophies for Sonic Generations when I stumbled upon it online and it was to no-hit the final boss on hard mode with no add-ons (in game stuff) and I can't help but feel that there's no way I would have known that's the trophy.

Do you like them? Hate them? Don’t care about them? Take pride in them?

What do you consider good/bad achievements?

Do they affect how you play games?

Do you feel you have to get most/all of them?

What games have used them to novel effect?

Anything else you want to say about the topic is fair game as well. This is an open door for any discussion related to achievements.
