Massively increasing player agency.
Decisions matter. Being stupid or lazy means you lose. Being smart and proactive makes you win. No longer ‘everyone gets a medal’. Stop moddycoddling pve in the name of new players.
Lower barriers to pvp such that new players (and players in general) can hunt older players. Give new players opportunity to fck sht up and be the villain. Enable rivalries to form between players by allowing foul play.
