For many players of massively multiplayer online titles, the crafting side of these games is especially appealing. Quite a number of EVE Online's players are drawn to the crafting side of this particular sci-fi MMO, and those in large corporations and alliances have learned how their collective efforts can allow them to produce vast quantities of items and reap equally vast sums of ISK.
EVE's crafting system is also very much the backbone of the game. Almost every ship and module used by players in the game was created by another player. Those who are into the combat aspects of the game are reliant upon the producers to supply their tools of destruction, and that destruction in turn creates demand (and fuels profits) for EVE's industrialists. It's an interesting bit of symbiosis (despite that animosity towards those on the other side of the fence) that keeps New Eden thriving.
