A Level Beyond

But if you want some real retro cred, say something about how Wanderers from Ys ripped off Tritorn.

No Luster Undimmed

That said, the final boss fight and the final boss theme remix are pretty dire. There, retro cred salvaged!

After long reflection and study, I think Ys: The Oath in Felghana might be a better game than Wanderers from Ys.
