What happens with AFK players currently? Particularly around vendors it can get a little congested, fading out AFK players might be of benefit in places like that.
I agree that AFK players should look somehow differently. It would be great if we could choose how we would want our avatars to look when we are not around. Turn into a marble statue, curl up like a kitty on the ground, fade to gray, make snoring sounds, turn into a hovering ghost...
different AFK options would be good. i think there should also be benefits for going AFK in particular locations [like in your house instead of in a public area, for example]
i like the idea of benefits for going AFK at home or maybe a campsite or rest stop type area, where you could interact with a bed or hammock or glitch-sized locker to take a short nap, or a big long snooze, or maybe even an extended hibernation!
doing this would unlock a special dream area quest or mini-game that is available to you when you return, and when you're done, you wake up from the dream. this would be fun because a) a glitch dream zone (different dreams of different giants maybe?) would be awesome, and b) it would provide an incentive to step away from the game and get some sleep or get some fresh air or get some work done, which hopefully will be an easier task as the game is on more often, but still. glitch dream zone!
