Behold, Realm of the Mad God!
Satiel and Aphmau give us some insight into this co-op fantasy MMO that has been become quite popular. An interesting twist on the classic MMO formula, RotMG throws the player into huge, pixelated worlds full of pirates, and beasts of all kinds. While most games encourage you to do your best not to die, this game actually WANTS you to die - well, kinda. Death is really the goal. Do your best, collect items, get equipment, slay the Mad God. Once you die, you are awarded Fame - and then the cycle continues.
Plus, it's adorable as all-heck!
