I would appreciate an improved demo-option as well. The main points have been mentioned before:
-get rid of the jumping/jerking around when prone/crouch
-allow us to see our weapon....(looks quite silly shooting people with nothing in your hands....mmm, use the force???)
-make demos work with tanks (the infantry demos are ****ed, ok, but the tank demos are more than that...
)
-options for fastforward/rewind/slow-mo would be nice
If you get this implemented, I might even buy a second copy just to show you how happy I am
