Nicholas Boulton, voice of Hawke in Dragon Age 2, and Ser Bryant/Vaughn in Dragon Age: Origins. (I killed Vaughn every single time, without even noticing the voice...) Also did "additional voices" for Witcher 2, and showed up in the Gridlock episode of Doctor Who. According to IMDB, "His talents include blues harmonica, slide-guitar, DJing, stilt-walking, scuba-diving, skiing, and kite-surfing. Nicholas is also a highly skilled horseman and swordsman."
Timothy Watson, voice actor for Bann Teagan Guerrin, Gamlen Amell, Ser Varnell and Lord Harimann in Dragon Age. I never seem to be able to pick out which voices are his until after I look them up - excellent work. =)
