Heart-felt fun as always, though a bit overstuffed with collectables
Contains all the charm and fun Lego games are known for, and some surprisingly quality nods to Tolkien as well. An excellent choice for casual couch coop. A few areas feel lackluster (Minas Tirith being one room, for instance, and lacking any siege of Gondor level), but overall the world is well constructed and relaxing to gallop about.
I'll say this though, the collectables are obnoxious and perhaps the numerical peak in the Lego series. Playing through the game you'll come across quite a few blocked off areas and currently indestructible bricks. At first this makes you eager to go back and satisfy that completionist urge, but the sheer number of them quickly becomes overwhelming. Unlike Lego Star Wars (where a thorough first try would net you the majority of a level's secrets), you'll probably have to play the same levels half a dozen times before being able to sit at a comfy 100%.
But don't let that dissuade you from an otherwise enjoyable game! It's unadulterated Lego fun and a quality escape for a few lazy afternoons.
