EVE Online - Factional Warfare @ MMORPG.com

With the Empyrean Age expansion factional warfare was added to Eve Online. MMORPG.com has an article about how it is implemented.

Most of the pilots involved in FW don't care about capturing territory; they just find the quickest route to where they action is, and fight. This is why Tama, at the time of writing this, has had one hundred and three ship kills in the last twenty four hours, according to the in-game map, overshadowing almost every other system in the region by a massive margin. Territorial fighting with no consequences has just led to most of those involved bunching up in a few systems and shooting each other for kill stats.

Now, problems aside, where can factional warfare go from here? Despite being the bare skeleton of a system there is a solid base here for future expansion, such as bringing the pirate factions into the fight. There's also the possibility of allowing player alliances to finally sign up, which was a major issue for a lot of players, as well as opening up benefits for the militia ranks.
