Retiring players and such
Additionally, and I feel sure this is in the pipe line, it feels like at least 1 additional update period a day for things like coach transfers, funds etc would make the game feel a little less static.
Oh and as a final point I've noticed in replays that the "players" totally ignore minion waves and what ever the other team is doing during replays. I don't know if that's just a visual bug or weather that's an issue of game mechanics but I thought I'd just mention it as a point of interest I guess.
Nice game you have here, lots of potential. Keep up the good work.
