Eh I've enjoyed MGS1,2, and 3 a whole lot. 2 and 3 are pretty amazing and I would say are 2 of my favorite games ever. Snatcher and Policenauts are fun goofy cool anime adventures. Never played any of the Boktai games and he's only a producer on the ZoE games. Though being involved with ZoE2 is a pretty big positive thing to me and either way those games clearly carry the Kojima Productions dna.
It's just MGS4 is one of the biggest entertainment disappointments ever for me. It's just really bad. Sure, I also tried to rationalize that it was good, but replays only make it clear how terrible in every sense of the word it is. The game itself was sterile. Sure, they finally got the gameplay up to say Gears of War 1 standards. It dosen't matter when everything else is so limp. The boss battles, the scenarios, and just the general failure of what sounded like such promising ideas. It was just terrible. The story is just the thing on top of a shit game. Whatever, I enjoyed the stories of MGS1,2,3. I know that won't be a popular choice on here, but whatever. They were fun and highly interesting. I'm not saying they were The Citizen Kane of gaming, but as comic booky GI joe fiction they were fine. MGS2 is still such a weird game with nothing else quite like it. It did all of the Bioshock series' shticks before Bioshock. But MGS4 kind of just takes a big shit on all of that with lame retcons, twists that are garbage, and character assassination.
PW is just a lame shitty game. Lacking in anything interesting to say or a charming personality. Such a dry game that plays like crap.
So yeah Kojima's gone downhill big time as far as I'm concerned. I wish he would move on from MGS and let someone else play around with it. Maybe the series could be fresh again and not have to slum around in the void of uninteresting prequels for the rest of it's life.
