What is it with Lego?

I'm not quite sure when it started, but at some point around last year I've been hoarding Lego sets. Big ones, medium sized, small... if I can I'll grab it and add it to my pile. I literally have two boxes full of unbuilt sets and I'm in a self imposed building ban until I can get hold of a place to store the finished ones. And I regret -nothing-about this. Except maybe not grabbing more sets when I had first pickings of extremely reduced water "damaged" sets. Who cares if the box is 50% tape and still soggy, as Lego goes they were dirt cheap.

...I do wonder why I have so many Star Wars sets though, because I'm in no way a dedicated fan, and if anybody asks I'll shrug and say "it's a space ship".
