There's a lot of interractions between players in multiplayer mode : Guilds, pvp territory wars, resources and informations exchanges, language, politics, economy, building...
The game will have a strong dominant roleplay ,but without frustrating players who would simply like to fight and play competitively ,they will be able to choose a faction in which they can compete against each other without suffering any malus or bonus.
As for players who wanted to play more in the atmosphere of the game,they can choose a simple citizen job so they will be protected by bonuses that will make others think twice before shoot them.
