I had initially attempted to create a poll that encompassed every single variable as an available option... but as you can imagine that would have created a ludicrously long list. While I was initially game for the sake of thoroughness, it was starting to mount up and I figured a multiple choice format would make more sense.
Anywhoo, for anyone not familiar with the voice cast selection, Jon Curry should be most recognisable as Zevran from prior DA games, Alix Wilton Regan as Samantha Traynor from ME3 (amongst a couple of minor DA characters from prior games), and Sumalee Montano is probably most recognisable as the Southern Belle Female #3 voice for The Boss in Saints Row IV.
Harry Hadden-Paton I have no idea... This appears to be his first video game credit and his career more so spans outside in TV and Film. Though even in those areas I personally can't say I'm very familiar with him.
As for my own selection, I was initially tempted at the idea of making a female Qunari mage with Alix's voice, because you can't get any more niche than that! However I think I'm still going to roll with my own bias and once again kick off my first playthrough with a male dwarf warrior... maybe a rogue. Jon Curry will be my voice of choice as he's got some awesome cords down that throat of his. Plus, dwarves in this universe seem to all speak with an American accent so it would make more sense.
That said if I enjoy this game as much as I hope I will, then multiple playthroughs will surely be in order! Hell even DAII was able to score two playthroughs outta me. I attempted a third, but... I've had all the Kirkwall I can handle.
