Here's a cool game i got addicted to. You make your own players, and try to win on a team with other players. Every game you get a specific amount of expereince and when you get 1k experience you level up and can assign points into different attributes that affect how well you perform in games. But the best thing is about this is that you can even see your player move in the game. The games are simmed and there are replays that show your guy running, avoiding blockers and go for the TD!

When you start avoid getting low demand players as you will have a harder time finding a team.
