Wooo, I didn't think I'd love this game as much as I did. Obviously I had high expectations because Kojima, but wow!
I for one really enjoyed the gameplay, but I totally understand that it's not for everyone. Walking simulator IS half right. The world is very beautiful though, so carrying packages on your back across the country isn't the worst. The gameplay mechanics to deal with the BTs feel original, which was just great. It's good to feel like you're playing something that's actually fresh.
The story is well... weird and beautiful and emotional, with great performances. Norman Reedus is a solid lead, but I gotta give it up for Léa Seydoux and Troy Baker. Mads Mikkelsen didn't disappoint either.
I do feel a bit conflicted with Kojima's tendency to use Hollywood actors in his latest games. Sure, they are good actors and games are a medium as much as any other, but I feel like voice actors and performance actors are already so ostracized in the industry, that Hollywood 'invading' this space as well might just make that worse.
Kojima IS a genius though, I become more and more certain of that with each release of his games.
