I never had a 360 or a Wii, so no games from these consoles. And still, there are plenty of games I'm still missing, like GTA V, the Mass Effect trilogy... sigh.
Also, there are some portable games that I LOVE, but none of them come close to the home console games, for obvious reason. It's hard to make a list including both really.

1. Pokemon HeartGold / SoulSilver
2. Final Fantasy XIII
3. Call of Duty 4: Modern Warfare
4. Call of Duty: Modern Warfare 2
5. Tales of Vesperia
6. Crisis Core: Final Fantasy VII
7. Catherine
8. Grand Theft Auto V
9. The Elder Scrolls V: Skyrim
10. Assassin's Creed II

Pulled straight from my top 50 games of all time thread. I feel like making changes though, it doesn't feel right not having Fallout 3, The Last of Us or Uncharted 3 on the list.

Their top 20 looked legit to me. Maybe replace TLOU with bioshock.

Will you do this again after Persona 5 is released? :P

1st : The Last of Us
2nd : Uncharted 2: Among Thieves
3rd : Ratchet & Clank: A Crack in Time
4th : Portal 2
5th : Halo 3
6th : God of War III
7th : Uncharted 3: Drake's Deception
8th : Super Mario Galaxy 2
9th : Pokémon Diamond and Pearl
10th : Ratchet & Clank: Tools of Destruction

I'm shit at making these lists ¬_¬

Same here, Fallout 3 just doesn't make my cut-off. A Top 15 would have been better, but too many points to tally then.

IGN's Top 20 isn't bad, but the order is Mass Effect 2 should have ranked much higher, and where was Lost Odyssey?

1. Demons Souls
2. Dark Souls
3. Dark Souls 2
4. The Last Of Us
5. Metal Gear Solid 4
6. Killzone 2
7. Uncharted 2
8. Radiant Historia
9. Crisis Core: Final Fantasy VII
10. Red Dead Redemption

Edit: Sorry had Lost Odyssey at ten but then I remember Red dead :P 

Btw The Last Of Us will probably win, In the last few threads I've seen similar to this one it has.
