I published my first paid game 9 days ago and I assume I will have to wait a little bit longer for it to get indexed. However, I have a few questions about the process and what information I'll get.

1. How long does the review take once someone has started looking at my game?
2. If my game fails to be indexed will I be notified? And can I fix any issues or do I only get 1 chance?
3. How does the wait time differ on my second paid game? Is it much shorter or about the same? 
4. My game is NSFW does that cause the indexing to take longer?

1. It depends. There's a queue.
2. You can fix issues so your game will be considered again, but communication could be better.
3. The time should be shorter the second time around, but that also varies.
4. Your game being NSFW shouldn't have an impact.

Hope this helps.
