Masocore

Masocore is a video game subgenre with a focus on intense difficulty, often featuring complex or unfair mechanics. The name is a portmanteau of "masochism" and "hardcore", suggesting that players of the genre are hardcore gamers who find pleasure in the aggravation required to beat the games and the feeling of reward afterwards for having surpassed a seemingly insurmountable challenge. Masocore games are mostly 2D sidescrollers, harkening back to retro Nintendo hard platformers, although the definition can also be taken to encompass fully 3D games of high difficulty such as soulslikes.
