Well....I'm going to stick out my neck here.
The only reason why I bought a Super Nintendo (a long time ago, but it was when the system was already pretty aged) from a young boy at a "Queen's day fair" was to play Super Mario World.
I haven't played many other games on that system, but to me, this seems to be THE game for that system.
In fact, it's still my favorite Super Mario game to date. On any system. It even comes in 2nd place to DK arcade in my "favorite games" list.....
But I probably missed out on a zillion great games....
Great offer and anyone slightly interested should jump aboard IMHO. However, I have to point my wallet in other directions at the moment...
