I feel like almost any new kit I look at is composed of big specially-molded bricks that would seem really odd and difficult to find a use for if they were deconstructed in a big box of bricks. Maybe I'm misremembering or am being too harsh on the newer kits, but I feel like the Lego sets I grew up with in the 80's and 90's were more reusable. I had the sense that every Lego kit I bought was also giving me cool new tools to build bigger/wilder spaceships and trucks, whereas these just look like a nice weekend project with no application thereafter.
