Atic Atac, Gunfright, Jet Pac, Knight Lore, Lunar Jetman, Sabre Wulf, and Underwurlde are currently (at the time of writing) still available to buy in the Rare Replay pack on the Microsoft Store. While it saddens me that these classic games are now owned by Microsoft, it is at least a good thing that they are still available to officially buy and play. Although only for XBox One and XBox Series X/S. Why no Windows?
