I haven't tested it out completely yet. I have played association and both times I finished a game, I got an communication error with the 2k servers. It booted me out of the association mode and didn't even save the results of my game or give me VC... pissing me off so I'm staying away from association for now
I played 2 quick games (5 minute quarters) earlier. I got 250 VC for playing and 10 for winning. My second game I didn't get anything so I don't know if there's a cap or if the game just glitched.
