I hate developers that add ultra-super-hardcore-hell difficulty achievements so much.
This meme is giving me flashbacks of Super Meat Boy's developer adding achievements in the console version where you have to beat the entire stage (20 levels) in one sitting without a single death. And that achievement exists for every stage in the game. For reference, one of the harder levels can take an average person over a hundred deaths to beat ONCE.
100%ing the game should be enough to get all achievements. That's what 100% means, but some developers just insist on inserting some challenge run nobody can beat into the mix.
