imo no disclaimer needed even if you had , not like it matters, not to mentions 99% of achievements are inherently worthless anyway, so the achievement (spam) hunters/devs doesnt really add or detract much anyway imo. -besides being super annoying if/when oneself is playing and suffering through it
pretty sure a few games have their achievements in such manner you actually don’t even need to play it, and can get it just from idling.
somewhat sure i even had one 100% from that; they came from teh moon ,
and ofc just a couple of others that lower your stats by only unlocking one/few that way, adding it to your list total “dragging it down”, since now you’ll actually have to play and complete them one day , questrun, camera obscura, cortex command etc all have those “launch the game”/“idle x minutes” bs achievements -worst idling ever…
