It's been mentioned before but I would really, really love to see Hands of Steel. It is such a crapfest I love it.
Perhaps a tin box Sergio Martino set with Hands of Steel, 2019: After the Fall of New York and Mountain of the Cannibal God?
And I'd friggen kill for a craptacular Bruno Mattei set featuring Strike Commando, Strike Commando 2, Robowar, Born to Fight and Shocking Dark. It would have to sell at least 13 copies I bet!
