Stubby was also AROUND in the 80s to see metal then.
What's interesting about the game is how the hair metal guys are clearly supposed to be still metal, but having "sold out". Their units are even exactly the same as your units, just colored to have zebra stripes, pink fuzzy handles, and leopard print. The other "factions" you fight against are pretty much goth/new wave posers (who admittedly have some incredibly metal units) and demons, who are also metal as all fuck. So It's still just a game about metal.
