One of the reasons why you want to keep a live-bootable operating system within one of your flashdrives or optical discs.
You probably need another device to securely boot up a live OS to recover your data. Don’t use Windows, because it might still be vulnerable to autoplay scripts when mounting your infected OS partition and I assume your infected OS is Windows, so the malwares are going to be compatible and unless you know what you’re doing, you probably don’t want to take that chance.
I love games that are story driven. Although if it does not have adequate interactivity, like meaningful choices and actions, then I would rather have it as a movie.
