Three things I think would make a monstrous difference. (They're all pretty obvious, but what the hell!)
- More edges/wickets gained by pace bowling in more realistic ways.
- Conditions affecting the gameplay - more spin in india, more seam in england, etc (if this would be venue specific that would be even more awesome).
- Some way of modfying batting so you don't have to pre-meditate the shot. (If you've got the reaction speed to wait till you see the colour and THEN play the stroke, you've got my undying admiration!).
Looking forward to it either way
