I really have my fingers crossed this game and the forthcoming Rockstar developed sequel for Red Dead Revolver really respark interest in the Western genre. It's an untapped market with copious amounts of potential, and, in all honesty, no one has gotten it right yet.
So check out the latest Call of Juarez: Bound in Blood trailer
which features a fair chunk of story so you know what you're going to be getting yourself into.
There's still a fairly unanimous vote the original Call of Juarez game didn't live up to expectation, but I reckon this one is shaping up to be pretty good, though only time will tell.
