We will not force people to rate sims. Ever.

If we did, people wouldn't be issuing ratings that they truly stand behind. They'd just rate it with whatever their mouse landed on, just to get the rating process done with.

Basically, it works like this: If you force people to do something, they usually don't give a shit about it. If you use a good method to encourage people to do something, they tend to take a lot more care when they make their decisions, and in general, the final quality is much higher.
