What I loved the most when I was a kid was Transformers, He-Man, GI Joe and Turtles.
I remember having this huge tier mobile base from GI Joe:

Also, one of my favorite sets was the Fright Zone from He-Man:

I remember this set came with a rubber snake which I could put my hand in. A lot of action figures was devoured by this snake. I also remember blowing it up like a balloon until it bursted.
An action figure I really wanted as a kid was the Transformer who could transform into a (grey) train and if I remember correctly he could also transform into a fighter jet. I remember I wanted it one christmas but I ended up getting Man at arms instead (He-Man). Pretty sad, as I hated this He-Man character and he didn't have any cool features I liked either:

The last huge playset I remember having as a child was perhaps the coolest of them all. The Scorpion from Transformers Decepticons!

This was a huge playset and it could of course transform into a huge robot as well. It had huge claws and storage rooms for other (smaller) transformers. I really loved this one. Also, I remember that when you had it in "scorpion mode" you could pull it across the floor and it would move just like a "real" scorpion.
I have probably forgotten about most of the action figures I had as a kid, but I'm sure you guys have lots more to share.
