Currently, the following is off-topic:
Speculative questions about developer intent, with respect to both mechanics and narrative
If the question is simply:
Why did Nintendo decide on four colours for the Game Boy?
... this question would be off-topic. Essentially the question draws in speculative answers... guesswork etc all on behalf of the developer. Whether this should be the rule belongs to another meta. However, this is the rule.
Now, the current question as it stands is:
Why did the original Game Boy have four colours?
How did the makers decide on four - and why not three or five? What is it about the hardware that made four colours optimal?
Was there a precedent to using four shades of grey in computer graphics before the Game Boy, or was this an invention of the system?
I am not so sure that the question in its current form is borderline. It is essentially asking developer intent (i.e. why did the developer design the Game Boy with 4 colours).
Additionally, the question contains a number of sub-questions, which make it look like it is guessing the reasons behind the choice:
- Why not three or five?
- What is it about the hardware that made four colours optimal?
- Was there a precedent to using four shades of grey in computer graphics before the Game Boy?
- Was this an invention of the system?
If a question was asked such as:
Why did the C64 have 16 colours?
How did the makers decide on 16 - and why not 32 or 256?
Was it because of this or that?
Shouldn't this be off-topic based on the off-topic list? I would also like to point out something else in the help-centre under the Don't Ask List:
To prevent your question from being flagged and possibly removed, avoid asking subjective questions where …
...there is no actual problem to be solved: “I’m curious if other people feel like I do.”
What problem does this question even solve? One day I was wondering why a piece of technology invented decades ago used 4 colours?
The way I see it is that the real problem with this situation is:
- The help-centre is not clear enough (specifically with regards to the developer intent reason not providing clear wording and/or examples)
- As a community we are not guiding popular questions with good answers away from off-topic elements (rather, we are closing it as it is, or fighting over how it stands now...)
- (Sorry for naming dropping) This whole Frank vs. the world comment war that crops up when Frank states why he voted to close a question (and the aftermath)... its very distracting and negative
The most obvious fix to the question would be:
Why did the original Game Boy have four colours?
How did the makers decide on four - and why not three or five? What is it about the hardware that made four colours optimal?
Was there a precedent to using four shades of grey in computer graphics before the Game Boy, or was this an invention of the system?
I think this question also needs some context along the lines of why is this being asked. Even if it is along the lines of trying to understand an article or documentary... I don't know. At least make it a real question!
As for the help centre problem(s), I think some work is needed, and probably belongs to another meta. There is nothing about Minecraft mod support, nothing about Clash of Clan "attack this base" - all being useful to add so that we can redirect users who fall foul of off-topic questions rather than to meta discussions regarding high voting "let's make this off-topic".
