What do you class as an average game score?

[SuperNova]

I go by
1: unplayably bad (gamebreaking bugs; unfinished levels; assets ripped from google images etc.)
2: Severe technical and qualitative problems, but technically playable to completion.
3: Just a bad game. It's not broken, or offensively bad, but it's mechanics aren't fun, the controls aren't tight, the camera is a nightmare and the visuals and story are nothing special or bad.
4: Below Average. There might have been something good in there, but the negatives outweigh the positives by far.
5: Troubled but cute, or a game wich reaches very high highs but is hampered by very low lows.
6: Mediocre, a game that is servicable but boring in all of it's aspects with nothing special about it.
7: Good game, nothing too terribly special though.
8: Great Game, fun to play. Coherent in it's game and visual design, minimal technical problems (i.e. no, 'fighting the camera, etc.)
9: Outstanding game, better than most. Tight enjoyable gameplay, outstanding story, great visual design, good voice acting, little to no technical problems, etc.
10: A truly special expierience. It might have problems here and there but the positives so overwhelmingly outweigh any negatives that it doesn't end up mattering.

So for me the 5-6 range is reserved for average games, with the 5 having more interesting but ultimately worse games than 6.
