(Skip this thread if you don't want even high-level spoilers) The overarching plot/progression is slightly amusing simply it essentially flips the concept from Ys VIII on its head. They introduced seafaring and nautical battles, which might sound exciting on paper, but feels boring in execution.

Getting from point A to point B initially takes forever and feels like unnecessary padding. Fortunately there's fast-travel to specific points from the get-go, and also sea currents that speed you up between specific places. Unfortunately it doesn't end with that...
