One quick question. I understand that Ys Origin is supposed to be a prequel to the other Ys games. How much of a spoiler is it for Ys 1+2? I hope Ys 1+2 releases here sooner rather than later...
You get a lot more out of it if you've played the first two games.
It's set entirely in the last dungeon of the first game, has a few puzzles that are throwbacks to ones in the first game, most of the bosses are reimagined versions of bosses from the first two games, most of the cast are ancestors of the important npcs in the first two games as well as the Ys goddesses being there (...though it's not like 1 tries to hide it that well to begin with).
it's probably not necessary
to play it first, but the continuity would probably enhance the experience.
