They already did. I thought Fallout 3'd system was great. TESV needs speech checks. Personality is so useless in Oblivion
That was one of my least favorite things about FO3, that you had pathetic "Good/Neutral/Evil" dialogue permutation choices that you had to pick, that words were crammed into the player's mouth through such dialogue permutatoins, and that permutations in the end are pretty useless. Besides, FO3 has nothing on a BioWare RPG's dialogue tree schematic. And for the record, nor should it. There's a reason that BioWare has vast and complex character interaction but no open-world no-boundaries exploration and relatively small worlds by comparison. Their focus is the characters. There's a reason that Bethesda has vast open worlds with almost zero boundaries and relatively small characterization by comparison. Their focus is on the environment and the world.
As much as having our cake and eating it too sounds nice, it's just not plausible.
Personality was useless in Oblivion because Oblivion had zero dialogue substance, and because everyone was filled with happy sunshine dust in Oblivion. Scantly anyone hated you and if they did, it was reflected in greeting only. Whereas in Morrowind, personality actually meant something, as you were constantly aware of how much practically everyone one the island thought you were scum without it.
As for your name, how about you write the sylables (Spelling) like if i was fred (I'm not)
Fr-Ed
I'd rather not have my character's name hashed together into a freakish Microsoft-Sam sounding voice synthesis. There's two ways to do something like that. The first is a synthesis a la MS Sam, all of which sound like a robot from hell. The second is to get a voice actor to record a huge number of sounds and half-phrases that can be strung together, but that takes huge amounts of time, money, and resource space, nevermind that it still sounds very robotic and insincere, as the sound-waves do not match one another in tone, pitch, and overall consistency.
Not to mention that it's impractical for large-scale syllable and vocabulary use.
