didnt realize this was an mmo
You play with peeps, you play against peeps, you collect gold and xp, you grind for uber heirloom items, you post on a community forum about the game and each other, there are a shit ton of servers, there are player found guilds/factions, and we fight for land and crap on strategus. There are also thousands of unique cd keys playing, every now and then there is a patch, sometimes new content...
Sounds like an MMO to me.
