Resources and time actually were an issue: once the Odyssey 2 was released, Magnavox wanted to drop it immediatly. So most of the games were programmed by Ed Averett, some of them are really good (especially the 4K games). There were also games programmed by other people, such as the excellent Killer Bees! programmed by Robert S. Harris. As for arcade ports, they were usually pretty bad: Popeye, Frogger, Demon Attack, Turtles and Q*bert were released for the system, and I think the only game worth playing is Turtles. In contrast, most of the rip-offs are actually pretty good, even if Alien Invaders-Plus! looks like a terrible clone of Space Invaders.
