Let's get one thing out the way; Lego Dimensions' supplementary packs are ludicrously expensive for what they are, okay? Okay. That said, where else can you find Batman dropping in to rescue Gandalf from the Balrog, see Lord Sauron take over Metropolis or take the fight to the Daleks with the help of Homer Simpson? The cavalcade of characters Lego's mighty chequebook has managed to entice are staggering, but the way they're combined for the base game's campaign is just sheer fun. You can tell the developers had an absolute blast conjuring up a tale where the sinister Lord Voltech captures all the elements of power in the world (Frodo's ring, Superman's kryptonite, etc.), forcing the world's heroes to unite like some inter-dimensional Avengers. Gameplay is exactly the same as Traveller's Tales have been putting out for about a decade now, but that also means it's the same stud-collecting, enemy-bashing fun, which when it powers a story where you're genuinely excited to see which property will make an appearance next, works a treat.
