Playing the game in Indian english accent I hope people from another countries won't take it awkwardly.

In Assassins Creed Chronicles, you play as Indian but its not AAA i guess.

It won’t restrict, but I’m assuming it would be optimised to work for specific angles.

Not really. It has more to do with the way I grew up watching movies in original language always. Imagine, you are playing a game set in Japan, with Japanese characters, real japanese locations, etc but the characters speak in English. It’s the biggest turn off for me. This goes for all languages, not just Japanese. Bong joon ho said it perfectly:

I dont thing any engine would restrict the devs to use a particular camera angle.
