This list is flawed. If a game has millions of players it is not automatically an mmo. League of Legends is not an mmo, it is a moba (massive online battle arena.) If we're going to use the flawed logic that LoL is an mmo simply because it has a large player base, then angry birds is also an mmo because it also has a huge player base. If LoL is being included then games like dota or smite should also be included. But they aren't. The list doesn't even have WoW or GW2 included, which basically define the mmo genre. Personally, I would vote EVE. Even if WoW and GW2 were included, eve has done a lot this year to improve the game quality.
