falloutttt: Play your games and have fun, and let others have fun their own way. Thank you.
mqstout: Exactly! Play the game your way and have fun, without chasing silly (and often disruptive or degenerate) e-peen measurements inserted by the developer to cater to a weird sect of the gaming audience who can't just play and enjoy a game without some external validation. (A system that originated as a "lock in and retain our audience" tool in closed systems, where it was sometimes mandated.)
Do you really think that everyone is buying/playing games just for the achievements ?
For sure there are some people, I guess, but that doesn't mean it's the same for everyone, friend.
Besides, you're not going to change the world with your comments, or even someone's mind for that matter. It is for them to realize if it is a problem, that they should be doing something about it.
But then again, I don't really see how it can be a problem. Even if they are playing games just for the achievements. If that's their way of having fun, after work or whatsoever, then they have every right. It's not like if it's gambling. Like loot-boxes and such.
