I've mentioned in one place or another how Jagex's browser game Runescape is full of ideas that the wider MMO field should take to heart. Today's Massively article on their clan citadels puts that into full view.

From the looks of it, Jagex may actually be ahead of the game when it comes to designing features for MMORPG's. Guild housing is a major requested feature that few games offer lately, (City of Heroes, SWG to an extent, Guild Wars) and this not only addresses that issue but gives players reason to do stuff in it with their guild. It isn't just a fancy space to appease RP'ers, it is a full fledged system.
Apologies for the lack of a full post today, but I felt the need to point that out. It was one of the first online games I ever played, and it still can surprise me at times.
