SMB3 wins 10-2.
Now, time for round 4!
The Legend of Zelda: Ocarina of Time (1)
VS.
Final Fantasy VIII (4)
The Sweet 16 is sure to bring some good matches, and the first one is sure to make good on this promise. OoT, the most consistantly and perhaps the most popular game around, looks as if it will indeed go all the way, but FF8 is a constant threat to FF7 for most popular Final Fantasy around. So this should be fun.
I vote FF8.
May the best game win.
