I don't personally but I have close friends who are or have been very heavy players. To me it definitely seems to have an interesting level of complexity, Eve seems to generate more unique and epic stories of gameplay than other MMOs, for example. You can basically decide what sorts of gameplay you want to engage in. If you want to work cooperatively with a bunch of friends and build cool stuff you can do that. If you want to be a soldier in a war you can do that. If you want to be a spy or a pirate or a fraudster you can do all of that too. And if you get tired of one you can switch.
