Personally i think Nintendo games are probably the most artistic games on the market, but since you asked for one. Legend of Mana is the absolute silver bullet that kills "game's can't be art". the game is pure art from the ground up and even passes the "this was clearly a labor of love and not made as a product" test because the game is such a mess you can't even say the devs intended it to be fun to play.
it's just gorgeous, arcane, and obtuse.
