Adding on Einhanders idea ( it is pretty different but related) i think there should be NPC guilds, They could be doing quests and you see them running around doing them, they could have weapons and maybe fight other NPC monsters, and they could also challenge players guilds to guild wars. They could have a set amount of members and the devs could make their alignments affect how they act towards players and other NPC\'s......for example: a good guild could protect players in battles if they are near or tell new players how to get started. or an evil guild could do the opposite, steal kills and try and decieve new players, and there could be guild wars between evil and good NPC guilds. This would provide entertainment and players could get involved.
