It's a little weird but this was brought up a few days ago when I was playing Dynasty Warriors (we had a really long wait before a match) and I've been curious ever since. What really IS an original MMO/MMORPG anymore?

More specifically, what specific Theme exists in the most MMOs out there today?

I thought about it for a while and I originally though Medieval/Rennaissance was probably the most prevelant...but I'm starting to wonder there are a lot of Fantasy, Sci Fi, etc. MMO's coming out and some older MMOs are starting to take a turn into a new theme.

So what do you guys think is the most common MMO theme out there? List a few games you see it in too btw, I'm really curious what you other addicts think :3...okay fine the moderates too >.>
