Good tips, but you shouldn’t answer “Yes” to the “allow users to purchase digital goods” question. Epic put together some FAQ on the process and that was one of the few questions they give you a definitive answer for.
In saying that, I’ve answered Yes to that question before I found the FAQ info and it passed. The whole IARC process is a bit of a mess right now and seems to be overly reliant on the person who’s reviewing the submissions on Epic side, they aren’t very consistent.
