I don't know Marston's Voice is a bit...odd to me, it sounds fine, but kinda...I don't know. There's something peculiar about it
I think it's the ruggedness of his voice? It's just not very common in many games. Specially in GTA games, and action games like GTA and RDR.
so far I've seen
Fist Full of Dollars
For a Few Dollars More
The Good, The Bad and The Ugly
Dirty Harry (not a western but it has Eastwood in it, and he uses a big [censored]in' revolver)
my Gamertag is Hagashager
Gonna watch High Plains Drifter tonight.
I've watched all those (excluding Dirt Harry) Outlaw Josey Wales, Once Upon a Time in the West, Unforgiven, Hang 'em High, Butch Cassidy and the Sundance Kid, and finally Pale Rider.
Damn those movies are awesome.
