emilyh: It's called flying on instruments -- keeping your eyes on your control panel, altimeter, and most especially your artificial horizon, rather than looking at the real sky; it's absolutely necessary at night in any kind of weather to prevent vertigo, and it works remarkably well for 3D video games, huh?

On Ladders: the best are actually the long ones, where you'd get 6 or 8 points of damage (before Deadfall) for falling. On those, do it thus: position yourself at the top, turn around, and backpedal off the top; as soon as you start falling, run forward -- on the long ladders, you should catch the ladder just when your characters start screaming, and you can then descent "normally". On the shorter ladders, there's really nothing you can do, other than hurl yourself Lemming-like from the top, because, with my backpedal trick, you'll hit the ground anyway before you can grab the ladder...

My experience is that the higher the resolution and the higher the framerate (number of screen refreshes each second) is, the less trouble I have with motion sickness. So a good video card and processor helps me.
Dungeons with uneven walls with little distinctive features are the worst, so in this game the boogre caves and the dragon spire.
It also helps to have enough light (apart from the monitor!), and take regular breaks. (Which I still find hard when immersed in a game. )

I had some trouble with that in other games and found that focusing on the map in the corner of the screen instead of surroundings helps.
