No contest, FFVII
FFVII was literally more instrumental in making me properly literate than school ever was, that and Pokemon, I got red version at like age 6, and FFVII at age 7, the heavy text taught me so much, it was better than any crappy game they make specifically for teaching, hell, I learned a LOT from FFVII, it gave me a massive vocabulary for my age, taught me compass directions, and tons and tons of other things I can't remember now.
