At least I was able to beat it I suppose, after my first unsuccessful attempt I seriously considered just quitting for good and watching the ending on Youtube.
I very nearly did throw my controller for the first time in years, it was so infuriating.
That said, it's still a good game overall, as I can't deny I greatly enjoyed 95% of my time with it. Just would've been nice if it ended on a higher note gameplay wise. If the fight had ended with the second phase the game would go from an 8/10 to an 8.5/10 for me.
I doubt the Astral Chain final boss is as infuriating as Wizpig in Diddy Kong Racing or Malos in Xenoblade Chronicles 2.
I actually think Xenoblade 2 is the last time I found a boss or sequence in a game this frustrating or unfair feeling; not just Malos but also the final fight against Jin was just horrible. Luckily that game also has a lot of redeeming qualities like its music, story, and most of its combat.
Bet with Liquidlaser: I say PS5 and Xbox Series will sell more than 56 million combined by the end of 2023. (And over 130 million lifetime)
