(Places on referee outfit)
Now, I want a good, clean VA discussion. That is, no belittling anyone else's opinions, no ongoing political debate on who Telltale should hire in terms of voice actors.
The main goal of this discussion is - who do you personally like as the voices of Sam and Max? Note that they don't have to both be from the same media. (e.g, you can say William Kastner as Max (current games) and Bill Farmer as Sam (Lucasarts era))
Heck, you can even say the 'comic era.' (e.g - none at all/self-imagined voices)
I actually really like Robert Tinkler as Max. (The cartoon series VA.) There's just something so rightly insane about him that he manages to pull off, and he has a wider spectrum of tone and emotion than the other two incarnations we've seen, IMHO. As much as I love Kastner, and his constant, manic chatter, Tinkler brings up a lovely rendition and variety. I really enjoy his take on our favourite lagomorph.
As for Sam, I'm actually really stuck on Telltale's VA, David Nowlin. He's got a range of emotion - but not too much, it's better for Sam to be semi-laid-back rather than overly enthusiastic. (Probably one of the reasons why I don't like his cartoon VA) Granted, Bill Farmer's probably the closest to Purcell's vision of Sam, but I just really like Nowlin's rendition. It maintains that passive 'manic' nature that Sam has, but at the same time, there's a little touch of (I'd say sweetness, but that sounds wrong. :/) that adds a little more dimension to his character.
