So when they said that you could field upwards to 6 or more characters, what they really meant was "Have fun playing as generic anime swordsman #0326 for the entirety of this 40-80 hour game.".
Also its nice to see that they wanted to make this series entirely Sci-Fi, they just also wanted it to conform to the standard swords and sorcery because thats what sells.
He didn't say anything about not being able to switch characters. I think the comparison was literally limited to the fact that battles start as you approach enemies.
