Voted for Greenlight, I'm looking forward to capping some fools. Lone (well kinda, with a few other hands) Guy takes down Crime bosses. This is basically wish fulfillment at work. :3
Or you can do it like some other games. Let him meet old friends that ask him questions that he can give different answers to and let players decide their character history
Make the protagonist a blank slate character, no one wants to be Sam. Let the player name him and build him however they want, this goes a long way to get the player involved in whatever story you want to tell.
You could give the player the option of picking a motivation/reason to do what he does out of a number of them, each option changing some missions and encounters, and maybe an extra final mission to solve their own story.
Subtle, ambiguous hints, that can encourage player speculation in a certain general direction is the better of the two options, imo.
Well...I didn't really want to say it, but Lhynn already did so I'll just second him and say I want to name Sam myself.
Blank Slate plis.
