Seems like a lot of extra work rather than 'don't install right away then delete the installer afterwards'... The GoG Downloader has it right where you can install right away or just give you the installation files. Blame M$ and Apple. Making their windowing interfaces where everything is mouse driven, where object oriented design although sound (like dragging files to the trash can to delete them) holds so much less overhead to learn, but you don't really learn anything useful. Performing most actions can only be done through GUI interfaces that have to be custom built and are sold to you piece by piece, whereas before with Unix and DOS systems, you were given all the pieces needed and you just combined them in a series of steps to accomplish the same goal. Yeah the mouse driven interface has made it easier for less technical people to use computers, but people have gotten lazy too and won't spend the 10 minutes reading a manual and instead want the specific issue told to them as a set of magic instructions they will never remember or understand to get the job done. Sad...
