I want to caveat my post by saying that I platinumed the original on Vita, its remaster on PS4, and the PS4 sequel. I put my time into each and every one of them. (The Vita and PS4 platinums were separated by years, and indeed, I played GRR as a refresher maybe a month or two before the sequel landed).
These games sucked, IMO. They are beautiful, gorgeous, poorly crafted collections of fetch quests stitched together by a borderline incoherent story. The second, in particular, offends me for having important things play out off-screen in stills and cutscenes while major set pieces are usually just waves of baddies occasionally topped off by a larger baddy. Or two. The only exception to this is at the very end of the second game, where the main conflict devolves into an anime body horror moment.
It had a lot of unique ideas, and flaws and mistakes that were kind of justifiable in an ambitious, open-world near-launch Vita title that just become unforgivable on a much powerful and more mature home console. GR2 also really angered me in that it took a protagonist I honestly loved in the first game and turned her into a complete punching bag. There was an element of this in the original, but it got ratcheted up to 11 in the sequel. It became downright uncomfortable to witness after a while.
GR2 has some minor refinements to controls and mechanics, but learned absolutely nothing from the original's mistakes. The combat, what passes for platforming, the mission design, and the open-world design are all just as dull and shallow as the first game's, and occasionally worse in some instances. And while the first game's story has a certain amount of charm and an air of mystery, the second's is just a disjointed mess topped off by a very unsatisfying conclusion. I think they knew they weren't going to get a third shot, but they still failed to stick the landing. GR2 also delighted in taking away your powers for too many side and main missions, highlighting further the flaws in the game's controls, platforming, and other mechanics. GR1 is a better and mercifully shorter experience, in almost all respects, IMO.
I'm sorry to say it, because I wanted to love these games so much. But in my opinion, they are extremely poorly crafted games with a lovely art style, gorgeous music, and unforgivable amounts of both jank and junk comprising the majority of my play time. There was an idea there desperately looking for a good game to realize it, and after 3 (I suppose 2.5) strikes, they're out. They both had atrocious DLC, too.
