Yep one server, but space is vaaaaaaaaaaaaaaaaaaaaaaaaaaast. Seems like most people have a "neighborhood" or Region they hang out in for the most part, you could play your whole eve life in one spot and not see the thousands of other people out there.

I like the one server thing. I think it fosters a more intimate community.

There are macrominers but its illegal (though there are still tons of them). The more you train your mining skillls, the more youll have to manage your inventory (because you fill up more quickly).

The people I play with... id say its 50 / 50 that have multiple accounts, most common is 2.
