The only toys my siblings and I ever needed in our childhood was Lego. The incomplete sets my parents bought in a garage sale when I was 3 were still in decent condition when I left home for college. Every additional set we bought (or were given) in the meantime blended flawlessly with existing sets, so none of it ever went to waste. Forward & backward compatibility at their finest!
same here, we pretty much only had lego (a lot was second hand) and stuffed animals as kids. now, for my own children lego and compatible bricks is the only thing that survives here. pretty much every other toy breaks after a few weeks.
