One of my all time favourite collection was Mattel's Secret Wars series based on the Marvel comics. So many cool figurines and playsets were released.
Remember Photon? I do! And always wanted one but it was too expensive back in the days.
The original Battlestar Galactica TV series was fun and the toys that came out from it were even better.
A few years ago, Hasbro released this ultra cool Marvel Universe Ant-Man!
Last but not least, this is probably the craziest playset ever released!
