Its Eve online. Its a space based MMO. A lot of gamers gravitate toward it because it includes a nearly complete player driven economy and production system, built in protections against some kid mastering the game on spring break (while us grownups aren't going to devote that kind of time), and a sandbox approach to play. It tends to appeal to the more intelligent gamer as well, the learning curve is somewhat steep. In games like wow you have "push button and bonk him on the head" type play. In EVE you have turret tracking speed, optimal range, falloff distance, ammo modifiers, skill modifiers and target factors to consider.
