Ghostwire Tokyo has a lot of potential. It's an original IP set in modern day Tokyo, but with an emphasis on yokai, ghosts and other Japanese urban legends. The Shibuya district is well represented, probably one of the best representations of Tokyo in a video game, after the Yakuza series.
It's full of cool visuals and interesting/strange decisions that make the game very unique.

It's all the more baffling that the game's design itself is extremely bland. It feels like a Japanese studio tried very, very hard to make the most tedious and forgettable Ubisoft game, with lots of collectibles, boring side quests and other filler activities.
The combat is also pretty bad. They're never really fun or challenging, and tend to drag on and on. Towards the end, I was actively avoiding enemies, simply because I didn't want to engage in combat.
The story is also rather forgettable, and I found the main character uncharismatic.

I think if you like the idea of exploring a virtual Tokyo and are interested in Japanese culture in general, this is a game worth trying. But the overall open-world design and the game design make it much harder to recommend, which is a shame because the art direction is too good for this game.
