If it's important to you that you interact with other players, then I don't think you'll be disappointed. I play on Gilgamesh, and whenever I shout for help there is always a helpful reply. Also, people are constantly looking for new members for their Free Companies, so it shouldn't be hard for you to find a group of people to chat with (and some even roleplay). If you go around doing fates and generally interacting with other players, you'll make friends in no time.
