wonder why Konami never remake a HD remaster for this game...

The GTA 5 "Who the fuck are they!!!?" cutscene. I was loling forever after that one. OK not epic but recently that was my favorite. Most epic may be Infamous 1 final cutscene just for the comic style and jaw dropping twist.

Terrible game, great cutscene.  It's actually two cutscenes separated by a battle(the battle isn't shown,) but they're pretty much meant to be one cutscene how it plays out.

The ending of last of us, when Joel does something basically had my jaw on the floor!

Any Heavenly Sword cutscene ever.

Until I can think of anything better, the OP's video. The fight between Sephiroth, Genesis and Angeal is just pure epicness.

When master Chief slips and almost falls off during the Halo 3 ending I almost lost it, I was sincerely worried about him and his fate. The entire ending cutscene is great but that one in particular got my heart pumping. http://www.youtube.com/watch?v=VybS1C-4CAk

you mean when he sniffs?  God damn that was epic.  Oh crap spoilers!

My vote goes to Resident Evil 3 Nemesis Opening,
first time ever gave me the feeling of "fight your way out of this nightmare"
