Cricket manager concept

[xixsoside]

Anyone can tell me what was the concept behind ICC and other similar simulation games. I mean how did the bowler take a wicket, what was the ratio or logic used. Did it only weight the potential and skills (like CM) or did it have other factors. How did the other factors participate.

I am hoping to build my own Cricket Manager game sometime and would be glad if someone could give me the basic design structure on which ICC's logic was built on.
