Most MMO's you see have good v evil, this v that (except Dark Ages of Camelot who had 3 sides) - I don't wish to see another 2 sided mmo with battlegrounds in the middle, its a very poor excuse for PvP.
I would absolutely love to see an MMORPG version of Eve, skill points system to skill up, no levelling grinds woohoo!!
Then you choose to join a guild, which captures and holds territory outside of "Civilisation", who maybe joins an alliance of guilds who hold several territories - people from outside the guild/alliance will be fair game for pvp if they enter those areas held by those guilds.
Guild/alliance warfare to take territory from each other.
In the Civilised areas, there are guards who protect you from being ganked etc, safe areas to hunt away from the pvp crowd. Maybe to trade, mine, forage, craft.
So yes, basically - an MMORPG version of Eve please - that would indeed be the most awesome of games!!
