They definitely wont get paid:
- Q. When can I expect to be paid every month?
A. We pay out by the 30th of the month following sales. For example, we will pay you for calendar February month sales by March 30th. It may take a few business days for the payment to post to your bank account. In that case, you may see the payment in your bank account during the first few days of April, following the example above.
Q: What happens if I don't complete my game?
A: Sometimes things don't work out as you planned, and you may need to discontinue development of your game. If this happens, you should contact Valve to figure out the next steps. Before reaching out, take a moment to carefully consider whether or not pulling your game down is actually the right choice. Are you acting based on an emotional response to negative feedback, or is retiring your game the appropriate next step? We take our relationship with customers seriously, so if you choose to cancel development of a game and retire it from the store, we will not republish it again later and we may offer refunds to any users who purchased it. Treating customers fairly is the most important thing to us. You can learn more by reading
