the gameplay is pretty well locked into place its a zelda game.....you play as link who slashes, picks things up, rolls on occasion, spins, climbs, swims, etc.
right before every level you get a new weapon which will be pivotal fighting the boss, and during the level you'll either have to fight mini bosses, a series of enemies, or solve some puzzle(usually involving your new weapon) to get keys, eventually you'll get a compass, a map of the level, and the master key. You will then fight a boss. There will be a fetch quest which will be fun, a collect-a-thon which probably wont be, and a new thing (ww + Tp) which i enjoy the cave of destiny. Throughout the game there will be side quests that get you hearts, and increase your wallet size.
the only thing that changes in a zelda game are the weapons, which usually have some genius gameplay gimmick, and there will usually be another new main character that will alter game play slightly. Like Midna, Kafei, Zelda, The Masks.
