Meh, I don't like it too much. It's possible to make your own, and if you had a lot of grey pieces it could be as big or as small as you wanted (And not have to spend FOUR HUNDRED FRIKIN DOLLARS).
[rant]Just imagine. Think about it. 400$. A Lego play set. Play set. 400$. The more you think about it, the more absurd it seems. Maybe if this was a bigger, more awesome lego set 400$ would seem OK, but this? No, definitely not for me. Think of all the other great things you could get/do with/for 400$. You could buy smaller, better Lego sets. You could get lots of candy. You could get awesome electronics. You could get an electric scooter, and still have money left over, instead of this. You could get a M1911. You could invest it towards college. Anyway, I don't know how lego could think people would be spending 400$ on this Lego set. I don't like it. [/rant]
