Normal is the best mode to play on. What I think so far is that the hard more is off balance.
Easy = more on batting(easy perfect shots when you bat) and easy bowling.
Normal = neutral batting and neutral bowling. (I manage to hit couple of fours and sixes, sometimes alot and sometimes just couple). I score big totals or sometimes under 100 or 80 and all out. In bowling, I get atleast 3 LBWs, atleast 2 bowled, and couple catches and just 1 or 2 runouts.
Hard = neutral batting but really hard bowling. (I batted on hard and scored over 400 runs with 6 outs but when I bowled, I managed to get only 1 wicked and the AI was on 378)
It is much much better to play on normal. Trust me, you will get much better gameplay than hard or easy mode.
