Super Mario world might be a bit long for one of these, especially since most of us probably haven't played it in quite a while. I mean you can always blast through star road, but that is an incredibly boring way to play. Unless you split the game in half and did it on two different weeks. On week do World 1-4 and 5-7 the next.

My vote:
Oct 30 - Mega Man X
Nov 5 - Super Mario World 1
Nov 12 - Super Mario World 2

And I would like to play X4 after, but we could probably give some other series a chance.

Sunday evening is one of the few times that I have a high probability of being free.
