Specifically, KOTOR I + 2, the Prince of Persia trilogy, some of the old LOTR games like Two Towers, ROTK, The Third Age, Def Jam, SSX Tricky. Just games I used to love as a kid. Had an idea in my head that the Series X would be a nice nostalgia box until some of its heavy hitters release. Most of what I want to play though a) isn't on gamepass, and b) isn't back-compat supported. The back-compat support from X360 on seems great, but I've played remasters of many of those games already (Bioshock, Mass Effect, the Ezio ACs etc)
