I'm 2-3 days into Origami King and the game is really good. The environments are amazing, jam-packed with stuff to do, puzzles to solve and stories to tell. The music is stellar. Like color splash, the game looks gorgeous. And the writing is superb and the characters are really funny and interesting. Olivia is definitely a standout partner in this game - I really like her - she's naive, witty, funny, honest, etc.
The game isn't perfect. The tutorials at the beginning are a bit drown out and I wish I could have skipped them. Anyone who watched the trailers probably knows how the basics of the game works already. There's also some weird resource mechanics where you have finite supplies of resources - like confetti, gold and items - but everything is so plentiful I am not sure why it's finite in the first place. It's a shame we can't control our partners in battle, but I don't really miss the loss the xp progression - the game has other ways to progress in the form of accessories, heart containers, items, etc.
As someone who loved ttyd and rpgs in general, I thought the puzzle-like battle system would bother me a lot, but it hasn't. Most battles are required to progress in the story, or at least make it so you don't have enemies chasing you constantly in the environment. Beating them is not pointless like some say because you have to beat them to progress in the story. Solving the same in-battle ring puzzles can get a bit boring and most of them are easy, but it hasn't really been such a major problem to drown out the rest of the game. The rest of the game is so great that the overall experience is still great. I really have fun playing it.
Oh, and the boss battles are a lot of fun and each one has different mechanics. At first, they are not too difficult, but by the 4th boss, things definitely ramp up. They hit like a truck too, doing 40-75 damage at this part in the game.
Overall, I'm really happy with Origami King. It is a game with lots of polish and love put into it. It just has so much charm, and it does so much so well. I would have given it a 10 if the battle system incorporated your companions more and offered more depth than just solving the puzzle, but I think the environments, the writing, the sound track and the bosses steal the show that I really do think this game deserves a 9/10.
I think anyone giving this game a lower score than 8 just because it's named "paper mario" but is not designed the same way as TTYD is being dishonest. A game needs to be judged on its own merits. It's hard to take these people seriously when the game could have had a different title, like "Mario's Origami Adventure" and it would suddenly have a better rating using their review standard. It's frankly a dishonest way to review games. For better or worse, the series has changed - it's been over 15 years since TTYD - the old rpgs games have essentially been discontinued. I miss them too, but that doesn't make Origami King an objectively "bad" game.
Part of me doesn't really understand how Nintendo fans of zelda or mario or metroid would not like this game - it's an adventure game like many other Nintendo games. Do these ttyd fans only play rpgs? If so, then I understand why they don't like it, but wow that's a pretty niche interest to only like rpgs on a Nintendo console while disliking all of the other adventure/action games Nintendo has on offer..... seems a bit biased/close-minded if you ask me. If you like Zelda, you would like this, whether you like rpgs or not.
