I've RP'd a lot in MMOs, and I can honestly say that out of all of the MMORPGs I've seen, AO simply has the most potential/best RPing community. The RPers are actually involved in the storyline actively and changing the world by how they interact with the LTCs. There's a lot going on, and there's a lot of "flavor" in the game and storyline inserted in various ways (some subtle, such as text on weapons and such).
There's a lot of room for creativity and flexibility offered in a futuristic RPG, I'm just continually surprised by the quality of RP in AO.
Having said that... you have to actually try. No offense to the Original Poster, but it doesn't seem like he really did.
