Japes and quips aside, I think that the two fundamental aspects of Lovecraft are:- Brooding, atmospheric fear and a sense of the unknown- The horror of discovering that humankind is insignificantAnd I think an MMO is really not the best place for either of those. A linear storyline, as in DCotE, is probably most effective for achieving Lovecraft's vision, rather than a sort of sandbox.However, if the whole thing were tongue-in-cheek, it could be brilliant. Imagine: you can be either a human playing a fairly straightforward online RPG, and when you gain levels you improve skills. Or, you can play as a monster, and you can change shape by spending XP. So you start out as a starfish-type thing (you know what I mean), move through Deep Ones and eventually become Cthulhu at level 100!And each monster could have a weakness. For "winged insectoid" from the Whisperer in Darkness, it could take extra damage from newspapers. Deep Ones might need to water themselves when above water. And perhaps Cthulhu is secretly terrified of mice.
