The website SNES Hub is going to do a top 200 Super Nintendo games article and needs opinions from the gaming community on their views as to what the top games are.
A poll was made here with a list. If you have games in mind that aren't on the list, there is a text box at the bottom of that poll page. You could also post your votes in this thread.
I think it would be interesting to see what the community at large views as the top games for the system.
