@RJ:

Yeah I guess part of it is the setting and people.

I did have my share of fun events in WoW back in the day, but being on a RP-PVP server it eventually just got drowned out by the PvP crowd. I could see it work in LotRO due to the setting, although I've never had a chance to try out the main EU RP server (friends elsewhere and all), I should get around to that.

You can't really enforce these anyways I suppose, the best RP is probably where it doesn't have to be enforced. That said, I wish it could be more "encouraged" in some way, you know where you stand with PvE and PvP servers, but RP is more of a designation of what you might find if you go looking than anything else.

Like you say though, there's more to that than rules. But I guess these are decent enough (common sense) guidelines.
