Honestly, Achievements are more of a guideline than anything. I typically play games that don't have Achievements, but a few like Minecraft, Skyrim, and Binding of Isaac give you a path for you to follow, if you want. I like it when Achievements tell you something new has been added, or you've done something wonderful! But I hate it when there are Achievements over stupid things, like finishing a key part of the story. I like knowing the optional content the game has, because the main story is something that is already set for you and stated in the game, so why put it in as an Achievement? Aside from like, an Achievement for beating the main story. One of those is fine. I am iffy about Achievements, but the majority of the time, I honestly just ignore them.
I get that. I recall a few games I own which a good 50% of the achievements are purely story, so pass chapter 1, boom achievement, it's a little ridiculous. I tend to find one that challenge you a bit more pleasing such as Team Fortress 2 some of their achievements are class specific, so backstab a few engineers as they remove your sapper, which you have to be a spy to sap buildings and backstab, but it is a good way for the developers to get players to try different classes.
