I noticed you mentioned the admin's love of RO. I have to say, looking at the screenshots that the 2D land and 3D avatars/monsters did resemble the look of RO. I believe you are right when you say there will be many similarities. And I rather like that, RO is an easy game for new players to catch on and old players to experience more.
One question I had, do you think they will get some Gaians to mod for them? I have just started looking into the business of Computer Games and found out the best way to get a foot in, is to mod for some games to get the experience of dealing with players and game issues.
