Not if you are using the script, which is what I specifically was talking about. As it installs ALL of the games. Ironic. As the post was asking for the script to be modified to ask what games to be download and installed instead.
As far as space, yes I noted it (the script) deleted the zip files after unpacking them. So you only ever have a single zip on your system at a time. And I also noted the 100gb was overestimated.
