dtgreene: I agree with 2 (except in a situation like Cookie Clicker where achievements actually do something in game), but only half with 3. In particular, I don't necessarily mind those that are hard, though I would mind those that take too long to get, or that violate certain game design rules (like an achievement that requires a long playing session).
I meant ones that are way too long or hard to get....where they're nearly impossible to get and/or take a very long time.
Like "Beat demon boss in diablo 3 in 90 seconds without getting hit on ultra hardcore difficulty" type things. Those sorts are near impossible.
dtgreene: For point 1, would you consider such achievements OK in multi-player only (or multi-player focused) games? For example, would they be OK in a game where the single player content consists solely of the tutorial and maybe a practice mode? To put it another way, would these achiements be appropriate for games that nobody would get just for single-player? (I agree about it being inappropriate for games with significant single-player content.)
I should've clarified....I meant MP only achievements in SP heavy games. I am ok with them being in MP only games(in part because I don't play much if at all of such games anyways).
dtgreene: * Secret achievements. I feel that achievements should be there to guide the player, and making them secret ruins that aspect. (It's OK to have non-secret achievements for which it isn't obvious how to get, like Celeste's 1-up achievement (especially since the game lets you earn achievements with assist mode enabled).)
I am ok with these being secret IF they contain spoilers.....but I think there should be a way(in game) to show their contents if one so chooses to be spoiled(before they get them, that is).
dtgreene: * Achievements that are outright broken due to bugs, either because it's impossible to qualify for the achievement, or because the game fails to register the achievement even when the listed requirements are met. (This is the sort of situation that should be fixed with a patch.)
Sidenote: This sort of reminds me of the glitch in Dragon Age with the glossary thing.....some entries(at least in the PS version) will mess up due to bugs, and they won't show the correct outcome of things like quests sometimes.
dtgreene: There should also be an option to reset achievements, for those who want to start over (for example, if one wants to do a 100% achievements speedrun, if it makes sense for the game, or even a low% achievements run (beat the game getting no achievements other than those that are impossible to avoid)).
Agreed.
This reminds me of FEAR 2, where one can collect documents, but cannot collect them in a second playthrough(though their contents remain in one's documents menu) unless one wipes the data(saves and etc iirc) and "resets" it.
