Eve Online has slowly being increasing it"s userbase over the past few years with a total of 130,000 subscribers, which totals out to be 1% of the MMO market. CCP (the developer) stated that the reason for it"s success is: "We also believe it"s due to the fact that Eve can be developed so modularly and therefore quite iteratively, that you could evolve core systems slowly. In the case of the change being in the wrong direction, we could easily revert or address that."
Kali will be Eve Online"s next expansion pack, hitting the shelves in September. Kali will be released in a number of modules: "The first Kali release will feature player Contracts," Richardsson explains. "Where you can now create enforceable contracts and practically create simple missions for your corporation or even outsource some parts of your operation to outside parties. It features Auctions, Escrow, complex Item exchanges for "Bring Your Own Materials" deals and so forth." Additional improvements will be voice communication, improved combat organisation and map.
