That sounds really interesting, although I don't think it would be for me, haha. I enjoy the writing because it gives you a bit more control on the situation, and I'm always wanting to add my own mark on more than just the character (Doesn't mean that it's quality though.). It's the same reason I enjoy the sandbox RP's more than the very heavily GM'd. It does sound like it has a very vibrant and big community, which I can imagine being extremely fun. Are there specific RP servers in WoW?
The slow pace is kinda nice though. I feel like a story would develop very differently, if people had to post faster. Post would be shorter too, so it will develop differently, although I feel in a game that whole pace thing doesn't matter, haha, as the whole world is better shaped already. Do you just don't do certain quests to fit your characters personality?
