2) The heavy restrictions imposed, meaning you can't edit the Australian and English squads, so the game will go out of date rapidly.
To follow up on this, here is the Australian squad as of August 2, according to Twitter:
Haddin, D. Hussey, Hastings, Johnson, Starc, Doherty, Bailey, Khawaja, Smith, Hughes, Maxwell, McKay, Quiney, Beer, Harris, Hilfenhaus, Warner, Cowan, Bird, Pattinson, Wade, Clarke, Lyon, Cummins, Forrest, Siddle, Watson, Paine, Agar, Henriques.
There are 30 players there. Given how different the 2020, ODI and test teams have become, it's almost certain that there will be players outside of that list getting a game over summer. Heck, whilst writing that I just realised that Fawad Ahmed is not there. Trickstar will likely come out and say "it's okay, we can patch him in" but what if someone else rises up quickly after Christmas?
Nathan Coulter-Nile? (played a 2020 even I think)
Joe Burns?
