This scale seem reasonable?
10 "I can play this forever and not be bored, with my friends" (Starcraft: Brood War, Warcraft III, Battlefield 2, Smash Bros Melee, any Pokémon)

8 "Playing this game with my friends is great" (Guild Wars, Halo 3, Turok:Rage Wars, Smash Bros Brawl, Perfect Dark, Timesplitters, Counterstrike, Mario Kart 64, Mario Tennis 64, Streets of Rage 2, Golden Axe)
7 "Playing this game is great" (Super Mario 64, Zelda OoT, Banjo Kazooie, Sonic 3 & Knuckles, Castlevania The New Generation or Bloodlines, GTA: Vice City, After burner II, Any Total War, Peggle)
6: "Playing that game was great. Replay? nah..." (Eternal Darkness: Sanity's Requiem, Final Fantasy VI, Starfox Adventures, Bioshock)
5 "Was alright, might play it again" (Gauntlet: Dark Legacy, Defcon, Age of Empires III)
4 "Was alright, don't intend to replay" (Zelda: Twilight Pincess, Turok by touchstone, Perfect Dark Zero)
3 "Haven't finished it and have no motivation to" (Final Fantasy XIII, Braid, Mario Galaxy 2)
2 "Got bored, stopped playing immediately, don't intend to replay" (Heroes of Newerth)
1 "This game is an insult to gaming"/"Betrayal most foul"/"The existance of this game makes gaming as a whole worse" (Ultima IX, Metroid: Other M, Command & Conquer 4, any shovelware)
I LOVE ICELAND!
