Some of them do. I install them in a windows VM then transfer them over to Linux.
I wish more pirated games were distributed in a portable manner. Saving a few gigabytes with compression is not worth the hassle of installation. It also ends up taking up more space because you need to have the installed version and the uninstalled one. Anyone who deletes the uninstalled version to save space is now no longer seeding.
The distro developers should implement a solution so that updating without enough space doesn't break your system. They could prevent the update or at least warn you that there's not enough space and bad things can happen.
Since the legal system will not bring justice to these murderers, it's up to heroes to do it instead.
