yes Gordon Freeman is a great example of The Blank Slate Silent Protagonist, as was Crono and Serge for the Chrono games... prolly why FPS are popular, as much as i hate them peeps prolly just wanna be in the heroes shoes feeling like its them doing the world saving and stuff, and what better blank slate than "nameless soldier" which gets the players name over their head in online modes further solidifying the connection they feel with their blank slate...
