For me, The Surge was an amazing experience. And I said that coming from the Soulsborne saga, bar DS2.
While I can agree with some of the complaints about environments or boss designs, in terms of actual mechanics the game is pretty tight precisely because Deck13 didn't try to clone Dark Souls at all. Yes, you have to be methodical to succeed, but the combat has its own traits and those traits work real nice. But yeah, if you play this game using your muscular memory of any of the Souls games, it will feel weird.
Having said that, I think this game is better than Nioh in various fronts but specially in level design. And combat in Nioh felt (for me) out of place for a game of this type. I just prefer the slow paced approach, and that doesn't mean that the combat itself has to be slow, as Sekiro has proven.
I'm really curious to see what they pull out with Surge 2. If the devs manage to address a few concerns (boss designs, mainly), it could easily become a sleeper hit.
