I've been buying digital DRM-free copies of games I own on disk here on GOG because they tend to run smoother than my old disk ones, but this old computer I have is running low on HDD (and pretty much everything else).

I'm asking this because the GOG copy of Sanitarium takes up way more HDD than my disk one, and I was wondering if, with only 11GB to spare, Psychonauts would take that much HDD space to install. My current Psychonauts folder is about 3.5GB.

Thanks in advance!

Thanks, that's all I needed to know! Well, if I uninstall my current disk copy of Psychonauts and install the GOG one it will be more or less the same, so it's all good.

Once again, thank you for the quick useful answer!
