Third
Ye... no. Greg server was pretty RP heavy before a ton of people fled to Balmung, many of whom did so to get away from one guy that only just followd them anyway (before he felt so unwelcome that he came back to Greg). Now Gilgamesh is just in denial, all the while the aetheryte in Limsa is surrounded by such . . . lovely people.

And then there's Levi where, apparently, there's a RP brothel, or was one some time ago; it made a substantial amount of money before an article was written about it. I'm sure other examples exist. Call Mateus the third RP server is inaccurate for that alone.

Mind you, I'm also unsure of the dates one these things, especially compared to this topic's conception.
