Eve online has some really good parts to it. SKill based game. Open market. Multiboxing is easy in that the gameplay is a lot slower (a lot of warping around in space ships). Beyond the fact that theres a follow command in the game its not very friendly for "true" boxing. There arent really key commands, its mouse based so you couldnt multiplex in that way. However, as I mentioned, the gameplay is a bit slower so its generally not hard to run a few characters at once.
