People.
A 6/10 is NOT a bad score with Jim. Not at all.
It is above average. Good.
The average score for video games should be around 5. Maybe just a tad more.
Currently it is around 7...
That is not right.
That's probably because most people think of scores in terms of school grades. It's pretty natural, really. People think of a new, abstract thing in terms of something else they understand better. The reason you have the '7-9' scale is because in school, knowing at least 70% of the material means you pass the class, and below that is considered failing. Shifting it down just fucks with people's heads, since they have nothing else to really compare it too. While a 6 means an above-average score, and that Jim liked the game, people think he's giving it a failing grade.
Of course, that's assuming you normalize the distribution of scores so that, by definition, 5 is in the middle, which means you have to compare it to other games, which is a bit of an issue if you have a big glut of shit games, since games have certain objective indicators of quality (technical stuff, like how it performs and controls). I have no idea how you'd factor in objective AND comparitive, subjective stuff into calculating a single score.
In short: Making a decent scoring system is hard and complex. Personally, I vote to scrap it all together since I, like Yahtzee, believe opinions cannot be properly expressed by a single number, but alot of people seem to like them and want to keep them, so we're stuck with the system we have.
