I loved my Lincoln Logs! I had so much fun building with them. I bought some for my boys when they were small, but they didn’t find them as much fun as I did.  I have 2 large totes of them saved for my future grandchildren. Lol
Slot cars.  I would hop them up, devise track layouts or just set up a drag strip.  I've even looked into getting one now for the kids and I to play with

                                        Slot cars was very nearly my answer. We did all those things.
The Aurora Super G+ cars. They were totally the shit.
Later, I did larger scale stuff at a commercial 8 lane track. Great fun, too.
@ScottAHurst Aurora Super G+ were almost like cheating after the AFX cars. Lots of fun though.
G. I. Joe, Star Wars, Atari, bikes. Nothing else really comes to mind. Transformers. Computerized things.

Books. Never was much for toys.

                                        Oh yes. I was a bookworm too. I still have a house full of them, although now they tend to make me fall asleep. Lol.
I had a terrific Meccano set: built lots of cranes and bridges and so on. But It wasn't a toy, really, and I never liked anyone referring to it as such. I think it is a great pity such things aren't available now.

                                        I actually had 2 favorite toys that worked together. I had a Lego block set and a plastic atomic cannon toy that shot rubber tipped missiles. I would build something with the blocks and see how many times firing the cannon it took to wreck it. That doesn't fit my personality but, hey, I was a kid.

                                        Scrap lumber, a hammer, saw, and nails. We had (and I still own it) about 5 acres of trees and another 10 acres of land where I could dig holes and build stuff including tree houses!
