Expect a lot of bad reviews from "Free to Play" at the end of the video and as a popular tag. They will expect an Free-to-Play MMO and not a free-to-play offline or private room (which there may not even be any when they come in to look).
Also, noting "In-App Purchases" might turn some away outright. This reminds a lot of MMO players of micro-transactions, or 'Pay for my little pony and extra bag space'.
Hope it works out, but just be aware if you start seeing bad reviews for these reasons. People are dumb.
