Clones

Smash Hit "Clones" (which may also be called Bootlegs, Rip-offs, Fakes, or Cash Grabs) are games that claim to be Smash Hit (or a sequel) or are obviously copying Smash Hit.

No known legal action (from Mediocre) has been taken against any Smash Hit clones.

They were probably made because of the original Smash Hit game's popularity.
