I found a cool hardware called Novint Falcon. It enables a new type of force feedback. Allowing you to feel bumps, textures, and other cool stuff like gun recoil.
It is hard to describe the controller but I am on the preorder list for their black falcon version.
novint.com is their website. Check out the videos of it.
When i get my hand on one. I am going to see if I can program mods to support it for older games.
