I would have to go with my all time favorite game A Link to the Past, that's the first game i ever remember playing and owning, so much memories and nostalgia comes back when i play that game, and its just such an improvement in the series that i just cant choose anything else, that's easily the game ive played the most times in my life and its what started me in general gaming and the Zelda series, it just have that special place in my heart and its never going away.
