Back in the day (must be 15 years ago?) at lan parties we would share steam game files locally if someone already had it installed. If the files were present locally in the correct forder, the client would be smart enough to skip to verifying the download.
I remember spawn installs! https://en.m.wikipedia.org/wiki/Spawn_installation - games came with the ability to install multiple multiplayer-only copies so that you only needed one copy of the game to play. This was invaluable for LAN parties but also families - this list certainly dominated the games that I played with my siblings.
It so often feels like things are moving backward <Old man continues to yell at clouds>.
Oh, I totally agree; I just don't think it's likely that Blizzard will be making another Warcraft RTS any time soon, and if they do, the story will either be some complete side-story with much smaller stakes, or they'll expect you to have at least some familiarity with the WoW story to understand it.
There's no need to yell at this particular cloud. Similar licenses still exist. For example, "It Takes Two" only requires one player to own the license. ...so does the "Jackbox Party Pack".
Also there are many local-coop games that can be played through Nvidia Gamestream. I played "Rayman Legends", and "Lovers in A Dangerous Spacetime" this way.
I remember CD games where it was MUCH faster to copy the install directory over the network than wait for the installed to decompress everything. And then a quick repair and you were good to go.

It still is; I just replaced the boot drive in my PC, pointed Steam at my already-installed library (on a secondary drive) and installed the games with no downloads necessary (other than updates for some games).
We would ask everyone to have the game installed and updated before they arrive, however inevitably the events would turn into "install parties". I still miss those days, though; if nothing else because I had more time and patience.
Steam is pretty robust.
If delete everything but steam.exe and the steamapps dir. Launching steam.exe will basically just reinstall steam in place and have all your Games there.
