We have a new American football management game at https://www.football120.net
It has a unique league system which you always guaranteed to play against a human manager, not some meaningless bot team.
You can watch the games play-by-play live, accompanied with diagrams and live stats.
Two league games per week. For other days, you have intra-squad scrimmage games where you can evaluate your players against each other.
For each game, you can set detailed tactics for each unit, role and player.
This is not a fantasy league game, no pay-to-win features, no unnecessary details like stadium expansion, ticket prices etc.
Transfers are done through blind auction. So you are not glued to screen at the last minute, nor rich teams outbid you easily. In addition to this, even though players have many attributes, neither of them visible. So it takes careful observation to succeed at this game, and at the same time, you can always steal a very good player out of nowhere.
