I'm probably preaching to the converted but I have updated my Xbox to TSW5 (deluxe version) and grabbed the free version for Steam, having bought the Humble Bundle of TSW4 recently. It suddenly occurred to me that I had TSW2 on Epic when it was one of their free games a couple of years back (and hardly touched since). Lo and behold, I can now update it to TSW5 for free, together with the base routes it came with. So if you've got that game lurking in your Epic library, don't forget to update it before October 17th.
