Very interesting game. I'm very glad that a AAA game this weird can still be made, but sadly it didn't land super well for me. I love the concept, and the lore and world building is intriguing, but the way it was presented was very boring to me. The cutscenes are fine, and some of the performances are great, the technology to capture the actor's emotions has come a long way. But, most of the interactions in this game is with NPCs who you deliver the stuff to. They're all just holograms who talk to you, Sam becomes a silent protagonist despite the fact that he's pretty talkative in main story cutscenes, thus making it all feel weirdly gamey for me.
Gameplay wise, I had a very good time. Really takes 'walking simulator' to the next level. Progression felt very nice too, with new vehicles, equipment and structures to build unlocked regularly as you go through the game. It was deep and fun, but also felt kinda janky. Especially with the vehicles. Something goes real bad with the driving physics when you drive over tiny rocks and such.
Overall, had a good time. The story, while intriguing, gets too much even by Kojima standards.
