There are a few companies out there that enjoy remaking slightly tweaked or re-skinned versions ofLego Batman Lego Batman - the same game, over and again – but there are only a few games that can do it and still keep it fresh. Nintendo does it with Zelda, Mario and Metroid. BioWare has done it with KOTOR and Mass Effect.
Traveller's Tales is now trying it too with Lego Star Wars (in all its iterations and forms), Lego Indy and Lego Batman – and frankly the cracks are beginning to show.
The gameplay is tired, dull and repetitive. There's nothing here Bit-tech hasn't already seen and what there is, just isn't as funny as it all used to be because they've seen it too many times. It's very much gaming by a formula – and this is a formula which has been done into the ground.
Overused and underwhelming, Lego Batman isn't really all that bad a game and if it's your entrance to the series then you may get a laugh or two out of it though it is by far the weakest in the franchise. If you've played any of the previous Legos though then now is a good time to move on.
