I think Mods, and even Minecraft are a red herring - they produce most of our issues, simply because of the sheer quantity of Minecraft questions, and because of the specific kinds of ways in which Minecraft fails, which are uniquely problematic, but not unique to Minecraft.
What kind of Tech Support questions are we good at, regardless of the specific game in question?
- Configuration - especially things like running games at non standard resolutions, or managing file locations.
- Clearly defined, reproducible gameplay bugs.
- Specific, well defined, and widely known issues, often associated with specific error codes, as opposed to verbose crash dumps.
What kind of Tech Support questions are we bad at, regardless of the specific game in question?
- Anything involving a crash that doesn't recur in a clearly defined, reproducible manner.
- Anything involving a verbose crash-log that requires significant effort and decoding in order to even have a chance at retrieving potentially useful information.
Which then leaves a fairly clear boundary for what kind of tech support questions we don't allow: anything involving a game crash that is not repeatable and reproducible. A sample close reason for this might look like:
Questions seeking Technical Support For Non-Reproducible Issues, as well as Technical Support Based on Crash Dumps or Logs are off topic. Without clear steps to identify and reproduce your problem, the Q&A format isn't an appropriate format for in-depth troubleshooting, and tends not to produce results that are useful to future visitors. Your best option is probably to contact the manufacturer of your hardware, or the developer of your game or any mods you might be using, as appropriate.
(Actually, that's 100 characters too long. Here's a shortened version that I don't like as much. Suggestions welcome.)
