On a ten point review scale, what number should represent an average game?

[Vinther1991]

It is objectively wrong to say 5 is the only average score, 5 and 6 are the average scores (or the ones that are closest to average), since 5.5 is halfway from 1 to 10. And no, 0 is not included, if it was it would be an 11-point scale, 0,1,2,3,4,5,6,7,8,9,10, that's 11 points.
