You stipulated FPP and voiced protagonist; and claimed that they didn't exist in the 90's.
There are plenty that existed without FPP.
There is a reason for that. Locking your development into a fully scripted [voiced] narrative, makes changing that narrative difficult. It also means that the PC's voice is fixed, and in RPGs that allow a wide variance, that poses a glaring problem. RPGs generally don't need a voiced PC, as everything the PC says passes through the player's awareness before they select it as their choice.
This is the idea; and how it's supposed to be... It is the point and purpose of it.
People can play any game however they want, but that doesn't mean that the game should actively facilitate or encourage playing it in any way other than as intended.
