I love all of the MGS series. Partly this is my own bias but I cannot find fault in any of them.I was disappointed with MSG5 largely because the falling out between Kojima and Konami basically left the game incomplete. Which is a shame, because the gameplay is quite good, and the theme of language as a form of colonization and cultural genocide are interesting. Also Kojima's star-f*!%ing led to David Hader's departure as Snake, which was a dame shame. Kiefer Sutherland is a fine actor, but he is not Snake.
Konami as a game company sucks these days, far more interested in their gambling machines than quality games. But given Kojima's work since the split (Death Stranding, which combined both masochistic, boring gameplay and a nonsensical story), I can't blame Konami for being a bit tired of Kojima.
Yeah I wish David Hayter voiced Big Boss in 5, but besides that, just truly epic. Even playing at higher difficulties isn’t unfair. It is just a challenge of skill. There is endless replayability in all of them.
Next I think i’ll replay MGS3 before MGS Delta releases soon. Hopefully that turns out good. Gameplay previews look awesome. They kept it exactly the same. As they should.
