It seems to me as if "Space Duel" from the Flashback 2 is really pushes the Atari 2600 to it's very limits, would you say this is accurate?
Great game ... but it's a little on the "easy" side (although this is mostly due to the generous amount of earned free ships). I was able to "roll" the score twice my first time playing it before quitting.
Stunning Atari 2600 programming!
