Some people will work through your achievements, no matter how many you have, 10 or 100. And some people won't work through your achievements, also no matter how many you have. Therefore it isn't exactly measurable and so "right or wrongs" on achievements can surely only ever be personal conjecture, based on individual experiences. And even collating these still won't necessarily give you an accurate idea of what will happen when
your experience is live. Do we not generally expect each new experience to be fresh, a little different and exciting from the last? So don't be afraid to do that!
It's your game, do what you want with it! Surrendering to popular opinion will only keep it firmly in the realm of standardized mediocrity. If you feel you've made a piece of expressive art then treat it as such and give it what you think feels right to promote that fact. If you're just a marketing department with a game dev studio on the other end of it, definitely pander to people's opinions and standard formats. There is no right or wrong way to go about achievements, so long as they work, everything else is just opinion and won't necessarily reflect those that are simply there to enjoy consuming
your expression, your experience, whatever you make it.
I really dislike getting achievements for simply reaching a certain distance in the game.
An interesting statement, considering this is exactly what you're doing for the entirety of a point n click - reaching certain distances, in the story etc - being rewarded with cutscenes etc at each milestone. You're rewarded in the game, and with Steam, you're simply rewarded outside of the game for, in some cases, sitting through godawful stories and reaching said points
Of course, if you're enjoying the story, and enjoying reaching the milestones, a little extra pat on the back for it from the Steam client isn't exactly a burden. "Reaching milestone" achievements are the base achievement type. My own personal opinion is that those are the very least a game should have in terms of achievements.
Even though they and other types of achievement may not be to everyone's taste, as a developer, it's also quite entertaining to see people find and unlock your achievements in Let's Plays etc. You don't have to like achievements yourself to appreciate they still bring other people some kind of additional joy here and there!
Still, for the record: I generally find myself playing a game once, and just get what achievements I get alongside enjoying a game for the first time, and if the game is good enough to be replayed, will work through the achievements I missed previously, because when you come to know the story and the outcome etc, there's still incentive (for me) to go back and complete/find things I missed. You find new bits of game, maybe additional mechanics you missed out on first time round. As a consumer I don't find this an issue myself...more bang for your buck! Arguably, with the linearity of some point n click games, this won't always be the case. Play it once and you've seen and done everything there is to do. But more and more even point n clicks are becoming less linear these days, and in some ways, that is down to rewarding different actions through the experience, whether that's in game or outside of game. And tackling linearity in any form is generally a plus. You probably don't need an achievement for every "Look at", but that doesn't mean a player using every "look at" can't be rewarded in some way.
