I just finished Sekiro and I really like it. It's an excellent new chapter in FromSoftware's repertoire. Still, I couldn't help but notice that it had some glaring design flaws. I'll share my opinion, and I would really like to hear yours.
My main gripe is in the way it often manages difficulty. Now, I just might be talking out my ass when I say this, but because its combat system is so streamlined and focused, the way that difficulty can be achieved while being fair and engaging has also become more streamline and focused. That is, there are fewer options, but when they are used, they truly shine (Owl, Isshin, Genichiro boss fights, etc.). However, I feel like Miyazaki, by trying to have near-constant variety, basically tried to have his cake and eat it too. A fair number of sections and fights in the game end up feeling either tedious or unfair or both because of it.
Ganking is the biggest offender here (especially you, Mibu Village and Headless Ape and Bride). Regular enemies here are, in my opinion, easily the hardest and smartest among the Soulsborne series. Most can block and deflect your attacks while unleashing unblockable ones that require precise counters, and you don't have the instantly-rewarding parry mechanic that the previous games had. Those, among other, reasons cause Sekiro to have the biggest spike in difficulty if you happen to be facing more than one foe, and Sekiro's own combat is not well fitted for crowd control, apart from firecrackers. Honestly, I mostly end up using the Whirlwind Slash against bosses rather than for crowd control, because the wind up is just long enough to leave myself open for an attack, especially if there happen to be snipers. It's especially annoying when the mini-bosses happened to be crowded by 4+ minions; it really just sucks a bit of fun out of it. Unfortunately, stealth isn't always an option.
And Terror is just plain annoying and frustrating. The game would've been better without it, or if it had been more frugally managed.
Camera plus tight spaces and flying/jumping enemies equals BS.
And finally, the Spirit Emblem mechanic should've either been scrapped for something better or been a bit more generous in the amount you could hold. I get that they wanted us to keep from spamming the shinobi tools and being strategic in their usage - I can agree - but that should've been balanced with freedom for experimentation. 15-20 is just too low, especially considering that Ninjutsu and other skills use them too. I was often afraid that if I use them to experiment a bit, I wouldn't have the emblems when I really needed them. I just often ended up feeling a little cheated, and staring longingly at all those cool gadgets available was not pleasant.
Those are my opinions. Please share your own thoughts.
