I’m currently playing it, and it is really addictive once you get into it. The only thing is if you find slugging items from point A - B - C back to A via B not so fun then you may struggle to enjoy it, as essentially that’s what it is. Traversing in the game is a challenge, as the whole environment is not smooth, flat roads/paths that you can go in a straight line, but instead you’re sort of veering off course and eventually get there. This is more difficult when you’re carrying all of your inventory, which this game takes a new and interesting direction in - basically it removes the magical inventory wheel/bag that most games have and instead places a consequence on how much you carry.
It’s an interesting concept though, and there are some instances of MGS present, but the main take away is that you aren’t Solid Snake, but instead you’re essentially a postman.
Classic Kojima in the cutscenes and the story it tries to tell, but all very good
