1. apparently do not mix.

Go to the outside area, and stand on one of the walkways protruding from the training center. Stand a little bit back from the edge, and jump straight up a few times. You will land in exactly the same spot you jumped from.

Now go to the very edge and jump. This time, you only move along the y-axis--so while you're in the air, the edge of the platform moves from under your feet very quickly and you fall a bit clockwise from where you jumped. (IRL you would be sent straight off the edge, not clockwise from it).

I'm not worried that this detracts from the realism too much, but I'm wondering how does this work out? Did Cyan program in some centrifugal force that applies to most of the length of the walkway, but not the edge? What is the physics model behind this behavior?

3. It to help you jump in straight lines. otherwise you'd go flying off to the left every time you try to jump to the piller with the journey cloth

4. It did just the opposite. For a while I thought that when I jumped off a moving platform, I'd go off at a tangent. So I would frequently jump too soon, then fall.

5. Dividertabs, you are right, but some laws of physics has been sacrificed in the game... when on the roof, you are in the rotating coordination system of the fortress, when jumping to the middle mesa, you are put into the coordination system of the mesa. The quest game is disabled now in the Live, but earlier its markers did not followed the above rule, and when using them on the roof, they behaved very oddly (the player's coordinates were constant relative to the rotating building, but the coordinates of the markers were constant relative to the world, thus their relative coordinates were always changing and it was impossible to catch them ).
