This is really a interesting way to play :
- weather is incredibly good. moving coulds, storm, clear or foggy sunsets, dark night or starmap night (can we find north with it ?

- mobs observation. This is kinda scripted, but... this is exciting. I sometimes go far from our main cities, places where mobs are "yellow/orange"-squared. You learn quickly which are aggro or not, and then you watch carefully what are their walkpath, how often and how fast they move... You learn how far they can see you, so you move, "sneak" carefully, (and sometimes you get stuck! lol)
You can start a zoologist career, it will be very useful for your guild/teammates

- tribes and outpost finding. Kinda trivial, but when you meet unknown tribes, it's fun to follow them then findout their outpost is hidden. Karavan spawn point too.
- Funny scenery. sometimes there is some "shrines" or just random stones, but very uncommon. Note them on a map and you can start a "tour-operator" or safari-like teamplay. This is very good for RP, and map-designer should increase the number of them. Missions should use them too. It's funny to say "let's meet together where the trees make a skull" etc...
When you are good enough to see really big mobs, and going to another races places (without prime root portals) this IS a way to play and have fun time.
But be prepared to get a huge death penalty !
