"I'm not hero. Never was. I'm just an old killer hired to do some wetwork"

I don't necessarily hate the post-MGS3 titles, MGS4 does just as many things right as I felt it did wrong and I forgive it more than I should cause I understand that it was trying to get the series out of the corner that MGS2 kind of wrote it into, but I also understand that it was Kojima's intentions to leave MGS2 as it was.

I always take what he says about ending the series with MGS2 (and MGS3 (and stepping away with MGS4)) with a grain of salt, since he's said elsewhere he always claims it will be the last one so that he and the team will leave nothing on the table, they won't get another chance to make a better sequel. An artists vision is only real when it's fixed (hence why that's only when we give copyright).

Honestly the plot in 4 threw feasibility out the window (on some points) but that was a tribute to MGS2, just like the game emulated MGS 1 and 3 in other ways (and even MG1 and 2). The game was less about satisfying fans with what happened after 2 than it was a celebration everything the series accomplished via showcasing the power of the PS3. It was more of a tribute game than a sequel, hence why it didn't take itself as seriously as some of the more anal fans did. The only legit grief I have with the game is the reduction of the Codec team and the B&Bs back stories being bed time stories via Drebin (bad storytelling).

Every other complaint I've heard about it has been fairly arbitrary.
