WB Games Lego Harry Potter: Years 1–4 - Playstation 3

Lego Harry Potter's gameplay is similar to that of most previous Lego video games, with an emphasis on collecting, exploring, and solving puzzles. Casting spells is an integral part of the gameplay, with a wide range of spells available for unlocking as the player progresses. As there are many spells available in the game, the player can use the spell wheel to select the spell. Potion-making is another integral feature; potions can help the player complete levels or, if created incorrectly, have adverse side effects such as turning the player into a frog.[6]

Changes to the mechanics of previous games 'Student in Peril' missions, which are a group of challenges to help a student, and Polyjuice Potion, which allows players to temporarily change one of the player's characters into any other mini-figure.[7] A major change is to the hub system. Diagon Alley serves as a hub for purchasing unlockable extras, The Leaky Cauldron works as a hub for returning to previous levels, while Hogwarts acts as a constantly evolving massive hub with the unlockable characters found by picking up their hidden portraitsB
