A good way to keep going, for the game to remain fresh and interesting, also fun which also allows you to interact with others is roleplay! World of Warcraft has it, and those players never get tired of playing the game, because they do it differently, they roleplay, they see things differently. And i believe this game allows roleplaying quite well. With so many interactive items, usables, commands and emotes, specifically the " /me " command really add depth to it. Let's not forget guild halls, with all the furniture, NPC's and pets.
Maybe some people are already doing it, i wouldn't know, don't spend that much time on the forums. Are there any guilds focused on roleplay?
