I agree that if you want to buy an resell a game new or old is not a problem an more power to you if you want to take on that risk for profit.
However I believe to keep pinside market a fair place for all, stats or reports should be available for review. I suspect there’s some old time shilling of sorts going on where games are posted for a ridicules price then gets a sale pending immediately then same titles show up for a slightly lower price still inflated which now looks like a good deal lol…
