Nuts and Bolts is a brilliant addition to the Banjo series. The challenges are very mixed and varied, and although they do start getting a bit repetitive after a while (But what can you expect from a game with literally hundreds of challenges?), it hardly becomes boring. The fetch missions, granted, are very dull, but thankfully they are outnumbered by far more interesting stuff. Whether you are a casual player or a gamer that really means business, you will thoroughly enjoy this game.
