My favorite scenes:

---Tifa and Cloud at the Gold Saucer- that whole part with her (I heard you can also do it with Aeris, but I tended to stay away from her since I knew she died- one of the downs to playing an eight year-old game for the first time when it's... eight years old)
---Tifa and Cloud off the airship before they go to the North Crater for the final time. Also just after that when she finds out that Barret, Cid, and Nanaki were all on the airship watching them. xD
---Cloud's conciousness in Mideel when he and Tifa fall in the Lifestream (yes, I happen to love that pair).

Also, as to whether Rufus truly died in FFVII- he didn't Unless, of course, the voice credits on www.AdventChildren.net are wrong. Also, you never found out if he died, that laughing couple only assumed he'd died when they received no answer from him from his office (they then proceeded to attack you with a really crappy mech and died). I'm certain he's alive, in fact (getting a bit into FFVII: AC...), because Rude is seen with the man in the wheelchair in FFVII: AC trailers, so I automatically thought that the man in the wheelchair was Rufus. We shall see if that's right. But he should be alive.
