I would try to keep Windows, go for dual boot. Then, from Linux, convert the partitions to a VM disk with qemu ( superuser.com/…/windows-10-uefi-physical-to-kvm-l… ) and finally use that, so that all the games installations are kept. This way, many other things will be available too, like browser’s history and so on. Making backups is cumbersome, I always tend to forget something. Of course, this alternative process is riddled with gotchas. But worth to try.
