Nice
For anyone wondering you can use https://ioquake3.org/get-it/ for most of these and just make a shortcut of the executable and add in target +set fs_game modname and it should work for most of them.
You'll probably need the baseq3 folder from a full quake3 install, pak0.pak to pak8.pak
I don't see why not, just mention SPTarkov in title.
