So, what games do you consider to be 10 out of 10?
That doesn't mean the game is perfect, because none will be, but that the game was SO good for you that you couldn't think of anything less than a 10 when you were playing it, and that you wanted so much that it wouldn't end and let you wanting for more.
I'll start it, I'll also try to make it in a chronological way, and say after the game which platform I played it (no need for it, just name them if you like).
Obviously I'm still to play A LOT of amazing games, so my list may always be incomplete, but what's here is what I'd contact with.
1998: Diablo (PS1)
1999: The Legend of Dragoon (PS1)
2000: Pokémon Crystal (GB)
2002: Digimon World 3 (PS1)
2005: Shadow of the Colossus (PS2)
2005: Resident Evil 4 (PS2)
2006: Bully (PS2)
2009: Demon's Souls (PS3)
2010: Red Dead Redemption (PS3)
2013: The Last of Us (PS3)
2013: Grand Theft Auto 5 (PS3)
So I've already gave the 10/10 score to 11 games.
What about you?
