After some weird release date shenanigans it seems like the game will actually release Nov 25th! (They can't possibly delay it anymore now right?) I've been really looking forward to it and looking at the reviews there's nothing to worry about reagarding the quality.
TheSixthAxis - 9/10
Steins;Gate 0 is phenomenal. Every part of it is bigger and better than the game that came before it. Rather than a tacked on sequel storyline that disturbs the perfect ending of the original, it explores a wealth of material hidden between that story’s many layers, and ends up creating a narrative that almost rivals that of the original. It’s a game that is, without a doubt, for a specific crowd, and while it’s inaccessible to newcomers, the entire point is to explore another side to the narrative in a manner that would be lost on new players.
Go and play the first game, because if you like that one, you’re going to love this one. And if you’ve already played the first game, well then, what the hell are you waiting for?
Destructoid - 8.5/10
Despite having a small number of grievances, none of them were significant enough to detract too severely from the overall experience. Simply put, Steins;Gate 0 is both a fantastic visual novel and more than a worthy follow-up to the first game.
HardcoreGamer - 3.5/5
Fans will be satisfied with how the tale running through Steins;Gate 0 is told with a narrative that rarely stands still in the present without coming off confusing. That said, the original’s degree of tension and regret over gameplay decisions are lost a little here and because of it, 0 — despite its successful transitioning, coming off more like a second half to a much grander tale as opposed to a totally sectioned-off story — often finds comfort in retreating to old techniques and former narrative inclusions to fill in the rare instances of figurative gaps. Even still, those who grew to empathize and connect with the main character’s struggles will find plenty of emotional tribulation here and as a result, Steins;Gate 0 can still confidently call the interesting fusion of scientific and romantic storytelling its own.
God is a Geek - 9.5/10
Steins;Gate 0 is the sequel I never knew I wanted. It is a perfect alternate take with various expositions for characters I know and love from Steins;Gate. The new characters are great and I’m glad I’m in a timeline in which not only does Steins;Gate get a proper sequel, but one in which it is localised so soon after release in Japan.
