Patrick's also made his mark on gaming (and on hundreds of hours of your life) as the voice actor behind Emperor Uriel Septim VII in The Elder Scrolls IV: Oblivion...
...even though [BARELY EVEN A SPOILER AT THIS POINT] Patrick's character dies early on.
Patrick's also the voice of Picard and Professor X in most of the TNG and X-Men games. And he established new characters by voicing Khelben "Blackstaff" Arunsun in Forgotten Realms: Demon Stone, King Richard LeGrey in Lands of Lore: The Throne of Chaos, Zobek in Castlevania: Lords of Shadow. At this rate his next game role will be Gravitas Guy in Fantasy RPG: Overwrought Subtitle.
By the way, Patrick's so good in games that [OTHER NOT-REALLY-A-SPOILER] his voice is the only redeeming thing in the whole tedious final stretch of Castlevania: Lords of Shadow. Seriously, if you want your Patrick Stewart fix from a shorter and more exciting piece of entertainment, watch all of Macbeth. With your parents. On Ambien.
