Henry Hatsworth in the Puzzling Adventure vs
Persona 4Wild ARMs 3 vs
Atelier Iris 2Either one is fine. I said in the last round that Wild Arms 3 has the best soundtrack in the WA series, but even so, I think it's still a bit overrated. Atelier Iris 2 doesn't have that problem, so I suppose that acts as a suitable tiebreaker.
Ys 7 vs
Tactics Ogre PSPIt's tough to top Ys music, but I'll side with Tactics Ogre for now.
Wild ARMs XF vs
Final Fantasy 8Wild Arms XF does have some good music, but I prefer FF VIII a little more overall.
NES Bonus Round 1:
Castlevania vs Ninja Gaiden 2
Ninja Gaiden 2 is a worthy adversary, but OG Castlevania is just too good.
Mega Man 2 vs Mega Man 3
MM3 is probably better overall, but I find that MM2's tracks are more memorable. They stay in my head a bit longer.
Here are
some extra Henry Hatsworth tracks if you didn't catch them in the first round.
