I am curious about the estate system, as presented in the wiki (http://themanaworld.sourceforge.net/wik ... tateSystem). I haven't really seen one of these in any of the games I am familiar with; in most, the player is just assumed to be a wanderer, and either sets up camp wherever (which then promptly dissappears when you log off) or stays at an inn (which is nothing more than a save point and a safe place to log in/off).
The system sounds fun, but I question a few things. First, where are these estates to be? Not on the main map, I hope; even modestly popular MMORPG's boast several hundred players, and that would mean either expanding the map or squeezing gameplay into successively smaller and smaller spaces, either one on a very regular basis as new players joined. The alternative, of course, is that each player's estate is in it's own small map, and these maps are accessed via common gateways (for example: the character walks up to and reads a "residence map," which lists character names, and clicking on a name creates a door/opens a portal/warps the character to the appropriate estate map). This seems to me the easier of the two, and the better overall. Then again, being unfamiliar with the system in general, there might be other options I'm unaware of.
Another thing is, it seems to be somewhat overly complex. The system of buying improvements, allowing/disallowing visitors, and having your "possessions" be safe from harm is all good, but butlers and gardeners? What would they be cleaning up? It would seem to me that it would be more of a difficulty to create a reason for them to exist than to just ignore it. As for the TMW "eBay," it sounds like a good idea, although I don't think that a broker should be needed; let the player do it themselves (and only allow the trading of estate-based goods on it; otherwise you might put the town shops right out of business

Anyway, other than that, it seems like an interesting system that could add an additional layer of roleplay (or chatting/meeting new friends) to the game.
