I've never regretted buying Legos for my kids. Yeah, the kits can be expensive, but they last forever. We've thrown out or donated lots of old toys, but the Legos will never be given away.

In terms of toys which my son got from my childhood, Duplo and Lego stick out. We kept everything; booklets and parts. We built the classic town square (set 1592) recently, and we've got all the parts, including the statue bits! Only the printed lettering on the sign's 1×8 white brick had faded.

Sure, some puzzles and books survived, but the Lego stands out. If he ever has children they are in for a treat…
