I checked and didn't see this video posted any time recently. To me, this re-edit captures more of the speed and ferocity you'd expect from Obi-wan vs. Vader while still remaining truest to the original footage.
Obviously, the question only applies if you actually suffer from thalassophobia (fear of deep water). Normally, video games don't really trigger the sensation, but holy crap, this game does. So much so that I find myself far more fearful of accidentally falling into water than falling off of a cliff. I don't suffer from acrophobia, so the heights never bother me, but that water, man...
...that water terrifies me. And yes, it's a 100% irrational fear (thus being a phobia). I get an instant pit of anxiety in my gut any time I'm around deep water in this game.
I know, it's not some major plot point for people to debate, it just randomly occurred to me and I felt like bringing it up.
Obi-wan's line from A New Hope, in reference to the lightsaber, is "Not as clumsy or random as a blaster; an elegant weapon...from a more civilized age."
While Obi-wan does refer to blasters as "clumsy" and "random", which we can argue is also just his subjective opinion of them, he's not really calling them uncivilized. After all, blasters were still the primary weapon across the galaxy back when he was a Jedi, and in fact they were in use all the way back during the Old Republic.
What Obi-wan is lamenting isn't blasters, it's the fact that lightsabers are no longer a symbol of the elegance or civilization that the height of the Jedi Order enjoyed. The "day of the lightsaber" is gone. Essentially, Obi-wan was just using the comparison of a lightsaber to a blaster as a means for him to segue into being an old man complaining about how things were better "back in his day" which is very much intentional on George Lucas' part.
To reiterate, I'm not criticizing the line. I chuckled at it, I got the reference. It's fine. I just think a lot of people misunderstood the connection and felt like yapping about it.
Edit: To clarify, because I suck at wording things sometimes, I'm not saying that the writer of RotS misunderstood ANH (because they're the same person), I'm saying that the line in RotS is based on the belief that Obi-wan was calling blasters uncivilized - it was George throwing in a little callback to ANH for the fans. This post is referring to the common fan misinterpretation, which the RotS joke only further reinforced.
