As much as Lego can seem quite pricey, for what is essentially bits of plastic, I think the Minecraft sets provide something a little different, which makes them better value. Little Minecraft fans really appreciate the detail that has been included, such as chests, fences, crafting tables, etc, which you couldn't make out of standard Lego. They seem to include a lot of pieces for the money and, with a few additional bricks, it is possible to join the sets together to make a bigger world. Below is Luke's own opinion of the set, along with an unboxing video review. It's longer than average, because he tried to include details on how to build the spider, as it is made of mainly standard bricks. Unfortunately it's not too clear, as I can't zoom on my iPad! Hopefully you will be able to figure it out if you need to.
Luke: The cave is a Lego MINECRAFT set. Is aged 8+, model number is 21113, and you can build your own creations, but inspiration is included. It took me approximately 25 minutes to build, but I say, other builders could do faster. It comes with 1 spider, 1 Steve + Iron pickaxe, and a zombie. It comes with 6 ores: 2 Gold ore, 1 Redstone ore, 1 Iron ore and 2 Coal ore and it also comes with building blocks and TNT. It seems to be quality, I did not at all have any problems with it, and I would recommend it to my friends as 5 star. It cost £19.99 in most places, personally, I would say it’s worth the money.
