Awesome Game Cutscenes

Some nice mo-cap going on here.

Old Rivals: Jin & Margulis - YouTube

Pretty much every FF scene already mentioned in this thread, especially the ones from FFX. In FFXIII I also like the reveal of Barthandelus. That "oh trout" look on the party's faces and that awesome battle theme kicking in is pretty sweet.

Also, this isn't that kind of cutscene, but I also like the scene that reveals what's behind the murders in Persona 4. All of the pieces were there for you to figure it out if you really think it through, but you didn't until that list came up for you to pick for yourself. From there, it's actually just a simple process of elimination; it can't be anything else. But you didn't have to resort to that, no. As soon as your eyes saw the right option everything fell into place in your head, and your head was probably thinking "oh no, anything but that" :(

Any cutscene in MGS3.
