I'm still confused how Barret's Gun-Arm can be concealed within that damned-tiny prosthetic arm.
Whether Vincent is jumping away from an explosion or using to the Flamethrower E.Skill to rocket himself up to Bahamut Sin also confuses me.
Originally, the concept of Bahamut Sin confused me as well. I thought he was supposed to be a corrupted version of Bahamut (even though he looks totally different) made that way by the inclusion of JENOVA cells summoning it (i.e. Kadaj). It was only after playing Dirge of Cerberus that I realized they were still adding things to the universe. Vincent's Galian Beast and Chaos actually changed (chop it up to evolution?), but the WEAPON didn't. The WEAPON was Omega, never introduced in the original VII. That's when I figured out that Sin was a completely different summon like ZERO.

The word "scene" cannot be applied to the motorcycle battle or any other battle. A scene is like a picture: it's brief. Tifa saying "Dilly-Dally Shilly-Shally" is a scene. The battle scenes strung together collectively are called a "sequence."

The coolest SCENE is Cloud's Omnislash V5 (hate the name), the coolest SEQUENCE, for me, is a three-way tie between Cloud's battle with Kadaj's gang in the CoA, battling Kadaj to that rockin' Jenova Death music, and battling Sephiroth while slicing through buildings threatening to crush any living thing stupid enough to be caught beneath them.
