As a mid-70ís kid, I grew up with LEGO sets from the 80ís and early 90ís: Town, 12V Train, Technic and Model Team. It must have been around 2010 when I dug up my collection from my parents place and instantly my interest was revived! I was overwhelmed with feelings of joy and nostalgia when I rebuilt 1592 Town Square, 7740 Passenger Train, 8865 Test Car and 5580 Highway Rig to name a few. In search of a way to document my collection, I discovered Brickset and from that moment on LEGO was (once again) a constant in my life!
Having said that, I donít buy a lot of sets. I restrict myself to large scale vehicles like the T1 and the ones in the Creator theme (actually, Iím still trying to get hold of most of them). Occasionally, Iíll buy a polybag or a discounted set that I find interesting for whatever reason (like the 9467 Ghost Train (to be converged to 12V) with many glow-in-the-dark pieces or the Tiny Turbos which have lots of attitude for being only only 4 studs wide!).
My favorite theme is Creator because this theme best represents what LEGO is about: experiencing that you can build many different things from one set of parts. I wish LEGO would stimulate this way of thinking across other themes too, like they did in the past by showing alternative builds on the back of the boxes. Luckily, nowadays thereís webpages like MOCpages, Brickshelf and Hispabrick which show what you can do with (even) a (very limited) number of bricks and a lot of imagination!
