I would love to se server which's world is growing up with it's players, but I think it's impossible as long as there are griefers around and admins couldn't know who to trust... however, PvP (and destroying or stealing the very valuable stuff) should be enabled only for opposing factions, but it doesnt mean "free for all", the factions must actually declare a war and suffer it (so defending by the weaker sides would be easier). Additionaly there shouldn't be any buildings made by admins, except spawn (community only! but it'll be impossible because of griefers), there should be faction support (something like guild vault from MMOs?) and some kinda trading system between factions so they could save themselfs from making wars. Thats all, if theres any server like this or will be, please inform me about that :)

As long as it's a private server, and I'm with my friends, it doesn't matter to me.Although, a bukkit server with some plugins that REALLY help the server is my favorite.By plugins that REALLY help, I mean things like Lumberjack and Permissions.

Defiantly Factions!

ADVENTURE MULTIPLAYER!!!!

A server with mods!
