Personally, as a customer, not a developer, this is disappointing to me, as there's still no reason for me to shop on Epic when they don't support my operating system, so this is likely just going to entice more developers to make me wait 6 months to play their games. Nonetheless, it's gaming news.
Epic already has a stranglehold on the dev side of the gaming industry, watching them flounder on the retail side is hilarious.
