I recently beat Knack 1 & 2 via local co-op on PS4, within the past few months. The first game isn't amazing, more like a tech showcase, but it's hardly terrible. Knack 2 is legitimately a good game, though. If you enjoy 3D platforming and beat 'em ups, and especially if you enjoy co-op gaming, Knack 2 is well worth playing. Mark Cerny did nothing wrong.
