Roleplay on Hyrkania can be found in /ooc. OOC is used for everything as there are no /rp or /advice channels. This is working well, regular roleplay, advice or normal ooc sessions springing up. We are a week behind Aquilonia so we are still finding our feet. Inns are popular for roleplay as are town squares.
AoC is rather a solo game, that detracts from roleplaying as I feel being forced to group increases roleplay. On the other hand the confined areas so many complain about actually increases roleplaying as you bump into people all the time.
Hyrkania is not free form PVP. It is zoned PvP, don't let that PvE tag fool you. But not being free form PvP gives us a freedom to roleplay I doubt you get on PvP servers. People are more prepared to take their time, something which will always encourage roleplaying.
