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.
I will never understand the animosity for the epic game store. A "launcher exclusive " means nothing, it's not like back when you'd have to choose between Mario or Sonic.
