You can get a Fuji X-E4 + XC 35mm f/2 for ~US$1000 new, and I'm yet to see a phone camera that can shoot something like this https://img.photographyblog.com/reviews/fujifilm_xc_35mm_f2/... - it's an enjoyable setup that will continue being ahead of any flagship phones for years to come. Not to mention that it's a hell of a rabbit hole and a great hobby.
Of course modern games don't run as portably. Spewing configs everywhere.
Most recently for a work social I resorted to a Google Drive share and bash scripts to get everything aligned. Still, played old games though; Doom and some crazy mods over Zandorum.
Dropbox also has LAN sync if you're all on the same "team" account. Works wonders between local computers.
I love seeing targeted solutions like the one posted by OP, but I can't shake the feeling that the application of distribution game files is only the surface of it's applicability.
