The best MMO names in my opinion are single words that sound cool or conjure up a strong association. I'm less fond of ALL CAPS ACRONYMS and any game that can't be more inventive with its title than to put "Online" after it. For the most part, MMOs play it safe and boring with titles, with only a few outliers in the awesome or terrible fringes. Today, we're going to examine the latter.
I want to make a couple of quick qualifiers here. I'm not judging these games by their names; an MMO can be good or bad independent of how silly its name is. And while I know that some of these names make more sense in context, I generally feel that if I have to have it explained to me, then it's a fail.
