Eve Online is a video game by CCP Games. It is a player-driven, persistent-world MMORPG set in a science fiction space setting. The game is especially famous for its massive "space battles", which often include over 1000 players fighting each other.
In January 2013, a very special event occurred. Consisting of over 4000 players, it was labeled in news (both in gaming media and non-gaming media), as "the biggest space battle in history".
I created an infograph for the battle, which displays the losses both sides took during the battle. It also features a very interesting detail of "total ISK loss" (ISK = Eve Online's in-game currency), which indirectly translates into 300,000-330,000 USD.
