It was a tough fight between lego and Sonic, but in the end I think lego wins.
Little building blocks to make whole worlds with, where spacemen could fight pirates and the knights of old rode trains through the city district. Where gaudy towers of blues and greens and reds and yellows stood tall amongst the lesser creations, where a house could become a boat, and the next minute a plane. Where landscapes changed from lush forests to barren deserts within an instant, and all who lived within these worlds had a purpose. And you were in it too, there was always that one lego person, probably kitted out in a ninja garb with three capes on, wielding a silver sword in one hand, and a massive laser gun that screwed up their balance in the other. No matter what the problem you built, your little lego person was ready to tackle it.
This love has stuck with me for 20 years, now the lego is being used to represent my DnD group, so I can build the dungeon rather than just use a grid and tiles. If there is a big dragon in the room, I will build a big dragon and put him in that room!
...If it wasn't so late I'd break out a tub and start building.
