12. Warcraft III - Arthas Kills His Father
http://www.youtube.com/watch?v=U5WWEi8XF6M Another Blizzard game crammed with brilliant cutscenes, Warcraft III contains one of the most effective stories of any fantasy RTS. In this climax of Arthas' story, he kills his father and seals his fate as one of the most memorable villains in video game history.
11. God Of War III - The End Of Helios
http://www.youtube.com/watch?v=M-cTlNHEL_A God of War III is one of the most brutal games ever created, and some of its cutscenes are violently gory enough to make anyone wince. The greatest sequence has to be Kratos' final encounter with Helios, in which he literally rips off the ex-God's screaming head. Nasty stuff.
