I played the Medium on Game Pass on the Xbox Series S. There's quite a bit of things that I did enjoy in this game, and a couple things that didn't work.
For instance, the overall art direction and atmosphere, I found to be very well done. The real world is well-made, dark and eerie, but for sure the spirit world is what was really interesting to look at.
Additionally, the story is quite interesting and explores more mature themes. The origins of the monsters for example, and what they stand for is quite disturbing. The game is essentially a mystery game in that most of the game you will be traversing the real and spirit world to unlock rooms, seeking clues and slowly piecing together more things about the story. Some aspects of the story will be obtained through collectibles, so it is possible to miss these, but most of this is for world-building and I do find that to be well done.
The main character is fine, but she frequently has inner monologues and also short remarks about various objects that you find. Some were fine, but there were also some that weren't and could be a bit awkward/annoying. However, the very few other characters in game were quite interesting, particularly when exploring their backstories.
Despite the overall atmosphere, the unfortunate thing is the game itself does not do well in providing real-time tension, in a sense that you rarely feel in danger as you are playing the game. The few survival stealth sections are few and far between, which quickly made me lose much tension, except in those handful of moments.
Ultimately, in the end what kept me finishing the game is the story is interesting enough, and kept me wanting to learn more.
I give it a 3.5/5 but rounding up to 4 since there's no half stars here haha. Can't say I would purchase this on the full-price as I don't think it's something you would replay, but it's worth playing particularly if you have Game Pass.
