Well, the critics would agree, lol.

lol man prolly not the place but I'd be happy if they continue metal gear and hopefully find a writer who isn't full of himself stuffing pseudo intellectual crap storytelling in what is otherwise a good game

but to answer yes i do see some reviewers being biased due to his absence

I still don't think there will be a next Metal Gear Game. But that aside, every review is always biased. Always. The fun of a game is just totally subjecitve. That is true for almost every aspect of a game, even for the graphics. Sure, you can measure fps and resolution, but that aside, every person prefers different art styles ans whatnot. So yeah, reviews for any new Metal Gear game will be biased, just like every review for any Metal Gear game was before and like every review for any game at any time was.

I believe it'll get unbiased reviews if the next MGS without Kojima is unbelievably good. If the game skips a beat, an important one, it will get creamed on the media.

Mario Party and Momotaro Dentetsu isn't related to Kojima. It's just that key developer of both game happened to get fired from Konami after Konami bought Hudson.

Mario Party 8 is last Mario Party Hudson worked on.
