The only two games that have anything even REMOTELY in common are Fable or Zelda. God of War is an action game, pure and simple. Zelda is an adventure game, completing dungeons and beating boss monsters, getting new items.
And Fable is a pure and simple RPG, with a lot of different mechanics added on top (mostly social things).

But to answer...The Legend of Zelda is my favorite.
The button I carry around doesn't necessarily make things EASIER...
