Just a little retrospective I wrote.
It is super interesting to me that there was a time when you could have a giant twist like this: a hugely successful prior game setting the stage for Solid Snake being a main character, then the ‘rug pull’ of making the following sequel feature someone else.
As I’ve read elsewhere in some comments, this kind of twist couldn’t really work today, with the immediacy of social media covering every facet of everything.
From the typical action star Snake to the over-confident Raiden, the shift was a big one for Metal Gear Solid 2.

But good lord was that leap in graphics a giant one for just a few short years!
I just wrote up a little look back at how/why it was done, and since I’ve got a terrible cold/sore throat, it was an effort. If you’ve got some nostalgia for MGS2, you might enjoy this one. And my question to you here, is were you there for this? Playing the intro on the tanker as Snake, settling in to what you thought would be a Snake-filled game, then finding out Raiden was the focus? Was it a shock?
Anyway, as ever:


But you still play as Snake. Sure, Venom Snake, not Solid Snake. But Raiden isnt Snake, hes just Raiden.
Perhaps Raiden is the reason that the MGSV protagonist is called Venom Snake and not something else.
There were a few MGS games that released between MGS2 and MGSV, and all of them IIRC had Snake as the protagonist.
Yeah, I mean MGS3 technically isn’t “Solid Snake”.
Cloning aside I’d like for major series like that to be okay with having more protagonists. It’s been one of Ace Attorney’s major issues; even when a new kid came around, he got show-stolen so much by Phoenix.
