I have not played that many MMOs at all.
In order played
--------------------
City of heroes/villians
Everquest 2
World of warcraft ( if playing for 15 minutes then deleting it because it was visually ugly counts )
Secret World
Champions Online
Other than the first one, I was dragged into all the others by friends.
I actually played Freedom Force before City of Heroes and, at that time, it was my favorite computer game of all time. It was AMAZING. I got to play a superhero with 3 other people at the SAME TIME. How is such a thing possible?
Then a year or two later I found City of Heroes in the computer game discount bin. "Nice", I says Another superhero game and it sounds a LOT like Freedom Force, from what it said on the back of the CD holder. Then I played it.
@.@ It was NOT like Freedom Force at all. It was like 100 gazillion times better! There were player characters actually walking around and interacting with each other. Yes, I had never even heard of MMOs up until then. But I liked it.
