Ugh, going back to 1 hour of programming a day is a real bummer. I should really think about investing in the lottery so I can stay home all day.
The free agency AI is taking shape! Player AI is all done, and seems to work pretty well. Player interest in your team take the following things into account:
1. What they feel their skills are worth, compared to your available cap space
2. Would they be a starter
3. Would they start on both offense and defense
4. Do they already have an offer that exceeds your cap space
That's the interest feedback you get from the main player window. If you've already made an offer to a player, he shows up in the offer window and the interest feedback is slightly different. That is the player's interest in the contract you have on the table. It's basically the same as the other interest, but the player also weighs your offer against other offers he already has.
If the interest goes down during free agency it's because:
1. He got a better offer than yours
2. You ran out of cap space
3. You ran out of roster spots
4. You signed other players and now this player isn't going to be a starter
Right now you can adjust your offer to increase the interest again. Soon you'll be able to cut players as well, to manage the roster during FA.
So far it seems to work pretty well. I'm going to start hammering through the team AI now, so I'm bidding against more than just myself, Twisters, Swarm, and T-Pain.
