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.
We’ve gotten disk write errors, but it’s basically always “oops we ran out of disk space”. Sometimes because we have plenty of disk space but the game is packed in such a way that steam needs the entire game’s worth of free space to apply patches (looking at you, Palworld!).
