In terms of the Atari at least, Activision must be one of the best software companies ever.Virtually all of the company's output for the Atari was top drawer (not too keen on Stampede!).No other company was that prolific.Ultimate PTG came close with their Spectrum output but a lot of their C64 games were tripe.

Very nice list. Defender II/Stargate has to be the best arcade port on the 2600 that I've ever seen. It is leaps and bounds better than the original Defender port.
