1. Completely agree with the other botb suggestion thread that chat would bring multiplayer to a whole new level of enjoyment. In addition to communicating status (eg. Brb or this is my last move tonight) you could learn more from other players and do some trash talking if the situation warranted it
2. An easier way to switch between active games. I am often playing an AI game while waiting for an opponent multiplayer move. There is a "switch now" banner or the gamecenter icon to move to the multiplayer but not in the other direction when you are in a multiplayer game. In other words, if in a multiplayer game - you need to go back to the main menu, then to play, then to resume to get back to your AI game. Would be great to have a popup list of all active games, including AI, that you could bring up from the active battlefield screen to move quickly between games.
3. Keep a win/loss record for each player that you have played in the past. It would be really cool to see how you do against other players over time.
4. When inviting a specific player to start a new game, show their win/loss percentage in each scenario so you could choose an opponent based on your skill level/desired scenario and goals.
5. Provide the ability to "flag" a player so you can remember to play them again at a later time. I now have many games over several days and don't recall who the more challenging players were.
That's all I can think of for now
