If I had a wish for christmas from GabeN or Valve in general, it would be actually meaningful error messages from steam.
If I had two wishes, I would like a community tool to share configs to make games work that require tweaking.
But I’d be very happy if I got better error messages.
That’s true, but it could still be more specific.
For example there’s a comment about symlinks on exFAT. Steam could say “failed to create symbolic link” instead of “disk write error” in that case.
There typically are a few different error conditions for normal writes too that Steam could pass on. E.g. on Linux there are separate errors for out of quota, files becoming too large for the fs they’re on, the fs being out of space, and low-level I/O errors.
