I liked Lego since I was a child.
Then I discovered Slizers and Roboriders and fell in love with this kind of products: built with technic system but with robots as characters.
Then Bionicle came and even when I stopped buying other themes and normal sets I kept buying Bionicle sets.
I'm not a huge fan of CCBS since it has some compatibility issues but I recognise its potential.
That's also why I'll focus mostly on certain themes and projects rather than others.
