Let me preface this by saying I do not speak spanish (ok a few words picked up here or there from living in Texas). I have however heard many native Spanish speakers from many parts of the world speak English. Puerto Ricans, Mexicans, Brazilians, Hondurans, Spaniards, Cubans and I am sure many more. I have heard enough to know there is no one Spanish accent. They are all distinct.

I had to hunt down video of the Voice Acting in question as I am not to that part of the story line yet. Just my opinion here. It didn't sound like any of the Spanish accents I have ever heard. I can't quite put my finger on what it did sound like but not Spanish.

Now to be fair. I generally don't expect much from gaming Voice acting. I am pretty good at suspension of disbelief. It is a fictional world with fictional characters of fictional nationalities that might loosely be based on real world ones. I tend not to get too bent out of shape when things don't match up. In fact this particular Voice acting might be easier for me to accept because it doesn't sound like anything real.
