1 - Abysmal - Haven't experienced
2 - Appaling - in the way a bad B-movie can be so bad it's funny. In comparison a 1 is just a frustratingly broken disaster - Rogue Warrior
3 - Mostly Awful - though there may be something appealing it's still not worth playing - Not experienced
4 - Poor - May have a good few things of worth, but it's flaws are still very prominent - Not experienced
5 - Mediocre - Rarely worth buying, though some may find it mildly enjoyable - L.A. Noire
6 - Respectable - Worth getting the occasional 6 if it seems like something right up your alley - Midnight Club: LA, Football manager
7 - Good - Worth picking up if you like the genre or premise - Dead Island, Need for speed: Most wanted, Civilization Revolution
8 - Great - Must buy for most gamers, always worth having a look - Pokemon Fire red, God of War 2, InFamous, Resistance
9 - Excellent - Genre defining, must buy in most cases - Uncharted 2/3, Civilization V, Half-life 2, Gears of War, Call of Duty 4
10 - Outstanding - industry gems, unforgettable experiences - Ico, Goldeneye, Journey, GTA: Vice city (Uncharted 2, Portal 2 and LittleBigPlanet are very close)
Note: I haven't included the .5s, I use those a lot and there is a significant difference between them but I didn't want such a long post.
