The Hard List

Completionists beware (and not just because "completionist" technically isn't a word)! Ever notice how pressing the "A" button is really easy, but pressing it a million times is really repetitive, boring, and uninspired gameplay? If so then congratulations, looks like you're smarter than the guys that made some of the achievements for these games! To be fair, some of the games are still great (Rock Band!!), and some of the achievements are just plain difficult rather than stupidly time consuming - but some are soul-sucking monstrosities that will leaving you regretting the mind-numbing multiple months and/or years you spent playing them. I've also included any games with completely broken/glitched achievements (✖), as well as those from the Shut-Down Server List (**) - in both cases completion is now literally impossible. You have been warned!
