I agree with @Chicklet453681
It’s too expensive to keep hiring all these actors. JtB was an exception due the brand involved. The simmified Star Wars movie characters needed to have a unique voice to match their life action counterparts and keep the player immersed in the world of Batuu. It doesn’t make sense for them to speak like every other sim in the world.
Since they’re incidental characters, also note that the studio recorded the lines necessary for this pack only. They’re vocal library is incomplete: there are actually a heap of simlish lines and reactions missing from Rey’s and Hondo’s voice.
I personally would love more accents and different voice styles added to the existing ones. But there’s a reason there are only 3 male, 3 female and 2 kiddie voices available to us (and toddle things). These are 8 actors that need to get paid for every single line in simlish for every new pack or updated content that includes speech or reactions. This is a ginormous list of sounds. It’s not only the actors who need to get paid, but the voice director, the sound engineers and sound mixers are also added to that list.
The kind of budget needed for even one additional and complete accent would be pretty steep and could be used for gameplay instead.
