Goldeneye wins 7-6.
Metal Gear Solid (1)
VS.
Final Fantasy Tactics (9)
Metal Gear Solid did what is expected of it perenially in Showdowns, which is trash anything that gets in it's way. This time, things get a little tougher, as Final Fantasy Tactics comes in hot off a upset of Metroid Prime. That said, FFT is far from the most popular Final Fantasy around, and the most popular final fantasy could probably not beat MGS. Therefore, it would seem to be an easy call here.
I vote...very hard, but MGS.
May the best game win.
