I bought a lot of these for my oldest son when he was 5 starting in 2013 when he got into Aliens. I get him 1 Kenner Alien or Predator each Christmas, and I will until I've bought it all. This year he got the Vasquez Night Cougar two pack unopened. Next year I'll do the Hudson.
He has the queen playset in box, the evac fighter in box, the stinger in box, tank in box, and power loader in box. They are all opened, but he took meticulous care of everything.
He has all of the Marines except Hudson and Omalley, and most of the aliens and some predators.
