It depends entirely on the game and the achievements. If they are skill-based, like a no-hit level/boss run (and I can get something out of it ) then I'll give it a shot, and I might be inclined to put a bit of extra effort into it. If it's something mundane like kill x-thousand enemies, or something I don't have the patience for like having to redo the entire game to get trinkets/a bad(alternate) end*, I might 100% it (if I like the game enough) but I won't bend over backwards to do it.
*If I am playing a game for alternate/true endings, it'd either have to be a VN or the game's replayability had better be damned good (like Hades good), or else it's just one and done, achievements be damned.
