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.
The error message should contain all the additions information, so that we don’t even need to parse and look into log files. There is no excuse for bad error messages.
