You're totally right. Kojima would have botched up a bit, and I think gameplay almost suffered due to stories. I actually find the story in Rising to be pretty solid, not just for the hilarity of it all, but some moments like Raiden talking to Jetstream, they were great.
I don't know if I want to see Solid Snake in another MGS with Kojima, all of MGS4...just shat on him. Seriously. He's old, he sucks, he's not even the protagonist. He's even demoralized easily - a freaking little girl takes away his cigarette and his psyche drops? That's not the Solid Snake I knew from 1, and 2. I almost want to play Twin Snakes just to have another go at Solid
And if he finds our posts, I'm not sure how to react. Flattery because he's noticing us, or horror because it might really turn into another MGS2
