In a sandbox design or at least a solidly sandboxy-themepark, you won't have that, since the very core of the gameplay & game world systems is specifically set to encourage dynamic, engaging, immersive, challenging player interaction w/ their world and w/ the PvE & PvP components of the game. It makes you CARE, it makes you EXHILARATED when you play, EVERYTIME, not just THE FIRST TIME YOU ENTER THAT ONE RAID etc, & it makes you WANT to 'win' whatever battles you fight in the game because they have intrinsically TANGIBLE rewards attached to them that actually change something in your & others' gameplay, not just 'candy' rewards that add +stats, +loot/game currencies, or +achievements/pets/mounts/titles/gear appearance options. You get tired of getting those themeparky rewards (the stats/gear/loot/pets/mounts/achievs etc type) after a while - because they don't really matter, don't really change your gameplay meaningfully. You already had tons of pets, mounts, stats, gear, great looks, tons of achievs, what more are these extra ones gonna provide..?? =/
