I don't seem to recall one, unless it was a couple of years ago. Transience's DS Game Contest has inspired me to do one concerning one of the greatest consoles of our generation.
Wouldn't be your standard 1v1 bracket, although it may be at the end, but more division based, and different formatted rounds etc keeping it fresh. Probably start off Round 1 similar once again to transience's contest as it seems to have worked pretty well.
If people are interested, i'll set up nominations later in the day.
Yes FFX may end up winning it all, but its THE JOURNEY that counts!
