How is Raiden in Rising, hated him in MGS4 and while he had his faults in MGS2 he was also integral to the story and its themes.
I actually liked Raiden a bit more here than I did in MGS4.
Regarding the camera - I'm a broken record at this point but I didn't think it was that bad, and if you use the lock on mechanic you can dance around some of the other issues. I had more frustrations with the DmC camera due to a lack of lock on and not having it automatically go where I needed.
I'm glad this game is selling well and I hope it keeps up (and doesn't drop off like a rock like DmC's sales did). Hopefully we get a sequel

Also, I'm in the camp that says no Gray Fox game. They'd have to dial down the 'crazy' and I think that would be a detriment to the game. One of my favorite things about MGR is how crazy everything is! Suplexing a giant Wild Wild West spider Metal Gear that's piloted by Super Mike Haggar was fantastic.
