Unique AAA Games, And Unique Game Aspects

[TallSilhouette]

Trying to keep to the last couple gens (earlier's too easy):

Interacting with a giant AI controlled animal - as the primary gameplay, no less (The Last Guardian)
A full ecosystem of mechanical animals to interact with (Horizon)
Good open world stealth (Far Cry 3 & MGSV) (FP & TP, respectively)
Play, create, share game and world building (MediaMolecule games)
Bring a pulp adventure flick to life (Uncharted)
Bring the Wild West to life (RDR)
Competitive painting (Splatoon, if it counts)
Portal, nuff said
