Easy to play, sometimes frustrating when you think you have what it takes to beat an opponent and you lose.
3D has made coming to the games a lot more worthwhile. Upgrading players is a little bit more money-based than I would like, but the youth academy and ways to earn tokens are quite creative and fun. I would like to see more variety in 3D gameplay, since it can get quite predictable after watching 5 matches. Counter attacks usually end the same way, every free kick being direct, rebounds being very rare, and yellow cards leading to corners feel a bit strange.
I will suggest you allow for automatic changes when players are tired and manager is not online to watch the game...If you could, do not let the game be interupted by the players conditioning. It could be a button that can be pressed to check and substitued. Also players training for other positions should be allow to play those positions while training to master it. It will also be nice showing a replay of goals.
