Well I played normal and won by a big margin but I can't really make sure TIE effects. It is so unclear to me as you can see my lost game. I TIEd 1 game at home last year and lost by a last second shot but still I am not really confident about TIE. I guess I will stick with normal since it will ensure my wins. I wish I could determine a little about how TIE will affect my ratings.
