I must have grabbed 90% of them, but honestly, I haven't downloaded or played any of them.
..and I suspect I'm not alone in doing so.
In fact, the ONLY game I've ever downloaded and played from the Epic game store is the one game I've actually purchased from them, Metro Exodus, and even that was a bargain £13 (with a £10 voucher) in the Christmas sales.
I now have Civilisation VI in my collection but I have absolutely no interest whatsoever in this genre of game.
But I guess its nice to know that it's sitting in my virtual Internet games library
