there is little point in adding teams such as italy and usa, because their skills in the team will be too, considering how bad bangaldesh and zimbabwe are. More domestic teams, more playes to choose your international team from, rather than just having a squad. Stats changing as you play (averages etc) encouraging to play better, and smarter AI, not harder to time the ball there is difference.
Smarter AI employs, better field placings at different times in the match, bowler selection, if you smash a bowler the AI will the change that bowler.
Bowler and batsman tiredness ie, you can bowl glenn mcgrath for like 10 overs straight, if you do he will bowl slower and more erratic, ALso injuries should be associated with this, naming a 12th man for sub fielder.
streakers, more run outs in ODIs , with use of 3rd umpire, realistic field positioning, for test, slips point only two men on legside, bowler bowls on off stump. bouncers that hurt and lead to injury, fielding tiredness etc. batsman running too much tiredness, makes slower in running.
Ability to control fielders, how they throw and which end they throw. Faster gameplay, means less focus on replays (unless you want them) , less commentary and faster gameplay. control fielders diving, sprinting etc - lead to overthrows,
there is heaps to improve EA sports arre pretty sh*t.
