Achaea was absolutely magical with everything being run by the players. It's still around, but I haven't played it since ca 2004.
Part of the immersion was how strict the RP was. You weren't even allowed to break character in the public chat. From the newbie guide:
In Achaea, you are playing the role of your character, not yourself. Your character is of the realm of Achaea and knows nothing about concepts like computers, the internet, the Boston Red Sox, or anything that does not exist in the world of Achaea. You must remain "in-character" (IC) just about everywhere. There are a few exceptions, such as in private conversation with someone else who does not mind if you go "out-of-character" (OOC). There can be administrative consequences for going OOC publicly, so be careful! If another adventurer warns you that you are exhibiting "insanity" or acting "insane", be aware that the word "insanity" in Achaea usually refers to OOC behaviour.
