I personally dont like the 1-10 or 0-100% scale. Its pointless to have the range that high when anything below 60% or a 6 is considerd sub par or poor.
Id appriciate more 1-5 scales and labels such as "pass" "rent" "buy". Its just more practical to real life judgement. Nobdy really cares about .5% of differences just if the game is worth your time and money.
