Bygfoot allows you to manage a team by training the players, buying and selling them, contracting loans, maintaining the stadium, etc. You can be promoted or relegated, even become a champion. It includes a "team editor" which you can use to create your own teams or edit the existing ones. The game is deliberately kept simple (though not easy): you only have to keep one eye at your players and another at your stadium.
