1) Pass (Ys is probably a great series that I am not at all familiar with. Ys III (S-NES) stumped me right from the start, giving me an uncertain opinion of it.)

2) Legend of Mystical Ninja (Very hard call to make. MM3 is amongst my favorite of games. But, it was a sequel to a sequel, where as Ninja was a first timer (in the US) and it had a lot of values driving it. I'm surprised that I've opted NOT to vote for the blue bomber!)

3) Pitfall (Considering the system, Pitfall is incredible. FF has newer tech, ideas, memory size, etc on it's side. But, I can't see a FF game making it at all on a 2600, where Pitfall succeeded.)

4) Pass. (I might have rented M&M at some point. Only played the demo of FFX. No opinion on either.)
