First off, I want to say that this question has NOTHING to do with the game I'm working on, Shady Brook. That game will have voices regardless.
I'm just curious, as a general rule. Certain games (mostly RPGs, but some adventures, too), such as Morrowind or Final Fantasy, don't have spoken text because of the massive amount of dialog and characters contained within the game.
So, my question to you is, would you play an adventure game if all the dialog was text-based instead of vocal?
I am REALLY interested in knowing, as a...future project, shall we say, might contain massive amounts of text, and I'm trying to determine if text-only is an option.
