Jaco Bredenhann :
That why you have achievements and play to receive bonuses
At the beginning you have achievements, but get to a certain point in the game and you've 'achieved' everything. Then there's little incentive. I then set out goals for myself ie. Get into top 50 rankings, be in the top league etc. etc. But I like the idea of rewarding (with gold balls) regular entry into the game.
