I always put 5 numbers in my comments as my ratings
#####
#1:Overall
#2ifficulty (do u like the difficulty)
#3:Playability (Is it easy to learn)
#4:Concept (obvious what this means)
#5:Length
I usually average the last 4 for the first
Why cant we get the other 4 bars to see what others think of the game's difficulty, playability, etc...
