CCP, the makers of EVE Online (which I've been sucked into recently) are going to be releasing a console-based FPS/RTS companion game called DUST 514 that sits in the same world as EVE. This is the first time anyone has attempted to integrate a desktop MMO with a console game, and I'm extremely excited to see how it develops.
EVE is the first MMO I've played since EverQuest over a decade ago. I have always been intrigued by World of Warcraft, but never jumped in. EVE's market-based economic and industrial components were compelling to me, though, so I'm giving it a shot. So far it is extremely engrossing.
