I like Steam achievements a lot - they are fun, and they keep you re-playing the game in all possible ways
'Bosch's Damnation' already has Steam achievements, but I think they are rather boring there - all of them are llke 'You've unlocked that door' and 'You've found that man'. They are all unmissable thus.
Mikael, Steam achievements could be either unmissable (story-related) or missable. Unmissable you get automatically when you progress through the game. And missable are those you have to do some obscure optional actions to get. The best strategy I think is to have them 50/50. So you would get some achievements for just playing the game in a linear way, but the rest you have to hunt for. Not like 'look at that strange object 50 times in a row and get awarded with 'You are too curious' achievement' - but like 'Find that strange object nobody usually finds'.
