Carpel tunnel syndrome plagued the world of gaming after Diablo making obsessive clicking an all-night event.  The dungeon crawler gave gamers an unlimited amount of replay with randomly generated dungeons filled with more treasure, look, and demons.  And if the click-click-clicking craziness wasn’t enough, developer Blizzard innovated some of the earliest and best online multiplayer through Battle.net.  Computer gaming changed for the compulsively better thanks to Diablo’s simplistic single click controls and some of the most addictive gameplay around.
