I'm sure a lot of you read siliconera, but I thought this was interesting.
I know this is Falcom's first original telling of the story, but this seems pretty far out there.
I never got very far in the original Ys IV (only played dawn of Ys on TBGfx) But I don't recall any amnesia elements, unless I'm suffering from it my self :/
This is interesting, I really want an Ys game to go in depth and elaborate as to how Dogi decided to leave and go on a journey with Adol, hopefully they go into at least a little bit of detail with this.
After all, I do find Ys IV chronologically confusing as to when it takes place in the series.
