Championship list:
1. Final Fantasy Tactics 5-0
2. Final Fantasy X 4-1
3. Shadow Hearts 2 3-2
4. Wild ARMs 4 2-3
5. Suikoden 3 1-4
6. Suikoden 5 0-5
FFT was an obvious #1 for me, though the 3 below it aren't too far apart and it was hard to actually choose between them. Suiko 3 isn't bad but clearly worse than the others, and Suiko 5 has way too many issues, while not being a bad game, to really be this high to me.
Note: I technically played a bit of TotA, but not going to rate it, despite the technicality of playing the full game =/= required, just playing some.
Super Failure Round:
1. Final Fantasy 12 6-0
2. Final Fantasy X-2 5-1
3. Final Fantasy Tactics: Advanced 4-2
4. Xenosaga 3 3-3
5. Dragon Warrior 7 2-4
6. Great Greed 1-5
7. Hoshigami 0-6
FF12 I like, FFX-2 is merely below average, FFTA more so, but neither are horrid. XS3 has really bad plot but that's less offensive than 100 hours of nothing (DW7), and horrible everything (GG and Hoshi). For the last two, I just Hatbotted.
