>>714502084 (OP)>the main draw to the franchiseWould you really call playing as Solid Snake that at the time 2 was released? It was a better time than any to test how a narrative from different protagonists perspectives would have gone.

You're asking this question from the benefit of seeing Snake as a celebrated character for decades already. People liked him, but it wasn't impossible at the time to envision MGS as something more than only the Solid/Naked Snake life story.
