Wii:
Mario Galaxy 1 & 2 (showed how 3D plataforming can be awesome)
Xenoblade chronicles (Best RPG last gen)
Zelda: Skyward Sword (The only motion based game i enjoyed, shows it can be done)
Wii Sports (The broad appeal brought a lot of new people in to the gaming world)
PS3:
The Last of Us (Story telling, character development, cinematography with a good enough gameplay)
Heavy Rain (While the gameplay is not as solid as TLoU, it is almost even in everything else)
Ni No Kuni (An work of art, despite the battle system being a little lackluster gameplay wise)
Demon Souls/Dark Souls (Showing there is space for challenge)
PC:
TES:Skyrim (Showed open world wonders and how important it can be to allow gamers to create their content)
CoD 4:MW (started all this FPS fest, even if i don't enjoy it, it had impact)
