7. Red Dead Redemption's Man With No Name Tombstone
Of course, an open ended RPG Western made by Rockstar Games is going to invite loads of references from the movies it's based off, but Red Dead Redemption does it in many clever and fun ways. The first time you meet the filthy estranged character named Seth, look for a grave around him marked "A Man With No Name". This is an obvious reference to the Sergio Leone films with Clint Eastwood, but something the gamer would never find unless they looked closely. This is the sort of thing that makes video games great for an RPG player. Discovering the little details of the world inside the game and every once in a while being rewarded.
