You're absolutely right, Obei. Some collision detection would stimulate some depth into this game. Walking through tall grass, climbing a snowy plain, faster speed when running down a hill. All of that would greatly feel the freedom of real life stimulation. I do not have a problem either with not being able to run through monsters. NPC and other people though? Yeah. I'd love to run through them. If you couldn't run through them, you'd probably be stuck in the markets or couldn't access your levequests since everyone stands there for hours.

All in all I think this is a great thread. This can sort out a lot of problems people are having with not falling down small cliffs, not scaling over simple mounds of dirt and debris, and yes even jumping, climbing, swimming, and everything else people wanted to see add more depth to the game.
