You cannot say ED it's not a MMO because, for example the 13000+ people that participated in DW2 didn't do it while being in a single instanceFor me ED is more like a interactive forum, uou move around looking for somewhere pf interest, sometimes your on your own in a thread and sometimes you see other people. Like most forum software theres a limit on the number of contributors at ay one time so you cant see everyone
To call it a MMO we need to look at other MMO games out there and tbh ED falls massively short of even UOs MMO capabilities.
Or because the 10000+ people that had built the Colonia bridge didn't do it while being all in the same instance

The common galaxy and everyplayer affecting that galaxy pretty much makes it a MMO
And i'm not even counting the thousands of people that are involved in the BGS or PP skirmishes on a very regular basis
