I got ending A and B and then youtubed C and D since I didn't want to have to grind out unlocking every weapon. The endings aren't that different really, the B route adds some stuff but doesn't actually change what is happening in the story, and C and D are more like Epilogues. The combat is fine, it's nothing special but I didn't hate it. Moving around the world is a bit of a chore though, and the jumping animation is one of the worst I've ever seen. Like seriously, who the fuck jumps like that? I feel the same way about the story, in that it's mostly fine but nothing special. There's moments where it shines, mostly in the dialogue that happens when you're running around and in a couple of small story sections (The forest of Myth is dope!) but I never connected with the characters or world all that much. The late game revelations and Route B stuff has some smart ideas but I didn't find any of it that mind blowing or emotionally resonant. There's a lot of cool ideas and I love the dungeon variety in the first half of the game but none of it added up to much more than that, a collection of decent ideas with middling execution.
After reading so many gaf comments saying it was underrated and the reviews were wrong I was left thinking "nah, a 68 metacritc seems about right to me".
