The Diamond Dimensions is one of Dan's more popular series, besides his mod reviews ( back in 2013, in Versions 1.6.+ at that series time ). The main goal was to go to other dimensions from the mods he added, to find new mobs, kill new bosses, collect new resources, and most importantly, to entertain us. He has 240 episodes, though the series has stopped due to his mod pack malfunctioning.
