Prefer it the way it is. S'more of a RPG/3D chat than anything else; you can create your own survival system through role-play, which boosts creativity and the like. The possibilities are endless - and the same old survival stuff you get with games such as WolfQuest can become a little repetitive after awhile unless there's some sort of objective/aim/quest behind it; but even then, it'd break up the community in my eyes, as well as the amount of role-playing that goes on.
And, being as I'm a lazy sock, I'd rather not have to get up off my butt every five minutes or so to catch food so my character doesn't flop from virtual starvation.
