If we pretend for a moment that this is supposed to be some sort of poll, then my vote would go as follows:

Kintyra - FNV Veronica

Oddvar - FNV MA4

(I think the "Martin" voice would make him sound like a 30+ year old guy. Which would be very... odd.)

Fortuna - TLOU Ellie

(The Kasumi-voice is certainly more catgirl-ish but IMO would get annoying before long. It would make her sound like she's overdosed on coffee or something. ).

Sinidars voice works for me.

Sidenote: I think the MGS Naomi-voice (choice 1 for Runa in the first Voice Test post) might work for Kintyra too. It would make her sound similar to Runa but given her backstory I think that would kinda fit.

Yeah, Kasumi might get annoying.  She sounds like she'd have a high-pitched voice though.  She's very small.

She might be quite small but judging by the last chapter she's also supposed to be a level-headed and pragmatic thief-apprentice, no? I mean, she was invited to join the TG officially but refused. So she clearly has what it takes to become a very sneaky kitty. She also reminded Kintyra to stay calm during the Haelga-scene. And the Kasumi-voice simply does not convey that kind of impression. I think with it she would sound too... impulsive? rash? overly excitable? Certainly not calm and collected. Aside from the "becoming annoying" issue.

Kyntara: FNV Veronica, sounds more real (and younger)
Oddvar: FNV MaleAdult4 (Tough one, I actually like the other voice a tad more, but it sounds to old).

Fortuna: The Wolf Among Us Snow White  (Another tough one, third voice is out IMO, the other two are very close ... and none get the name right or is that how you want it pronounced?)
Actually, for some reason, I could see Fortuna using the Lara Croft voice. ^^

I'll check out the Lara Croft voice, have it available. 

The pronunciation- I can spell it phonetically and they'll gdt it right, but I made no effort to do that.
