A fair few titles in the early days of gaming were shameless clones of other companies’ work.

Atari’s Frog Pond, a game that ended up not being released because Atari wasn’t willing to spring for a monster 8K cartridge for a “children’s game”, was a clone of Mattel’s Frog Bog for Intellivision (which ended up being ported to 2600 as Frogs and Flies), which in turn was a clone of Sega’s arcade title Frogs.
