When comparing to reality, time travel is illogical, magic is illogical, etc.

You do not know what illogical means. Such things are not illogical in and of themselves. Believing in them, against all evidence and logic, IS Illogical.

Not to mention that the game / contradictory books mention nothing of relationships between Rinoa and Ultimecia. This is a Final Fantasy game. Fantasy world can lead to infinite possibilities! In VIII, there's no strong evidence that R is not U.

And there's no strong evidence that Cid isn't a killer cyborg. Your point?
We only work for what there IS evidence for, and the bigger the claim, the bigger the evidence.
Also, contradictory books? Does someone not like the FFVIII Ulti killing his pet theory?

That still doesn't explain how/why players sense a bit of R=U when playing VIII. A lot of players have sensed this... and of course they deny it in the end because it's silly and embarrassing! They apply common sense and logic to VIII too much...

They deny it because it's narratively bankrupt, supported by no substantial evidence, and utterly nonsensical.
And are you actually trying to tell me common sense and logic are bad things?

Explain why the book mentions something about the lifespans of sorceresses? Was it to hint that R cannot be U? If so, then it's still a contradiction because there are certain things in VIII that are pointing at R=U. It's not the first time that Ultimania has contradicted something.

It was to explain the confusion arising out of Edea's line about a sorceress not resting in peace until she's passed on her power. That is renders the R=U theory impossible is NOT a 'contradiction' with the game, it simply means what you thought were hints towards it are not.

Time travel is impossible in real life, and yet it is possible in VIII. The VIII world has many more possibilities and less limitations than our real world.... so why not?

Because there's no concrete evidence to support such a patently absurd notion, it would require Rinoa to jump forward an absurd amount of time after the events of the game, not remember who she is, and turn evil, ignoring Ultimecia's actual motivations and backstory, such as it is.

Well, yeah. But if a lot of people have noticed a piece of R=U while playing VIII, then it's just more than Sephiroth/Barret or C/T...

Not in the slightest. A million people can be just as wrong as 50. This is pure ad populum, and not even cited ad populum.

It's relevant! For example... #1 person and #2 person:

#1 - Hey, I just started playing VIII...
#2 - Lucky you!
#1 - And I was wondering... Is it true that Rinoa becomes Ultimecia in the future!? :eek::eek::eek::eek::eek::eek:
#2 - Impossible, impossible, impossible, impossible! Not true.
#1 - Oh ok, thanks!

Then that #1 probably will tell his friends or new players whenever they ask such a question...

Rinse and repeat!

There's this FAQ on GameFAQS that discusses about R=U by Sir B, of course. But there are too many lazy players and I doubt they will read the FAQ since it's a pretty huge white paper...

AND? Look, you say there's gotta be something to R=U because a lot of people believe it. But a lot more people don't. EVEN by the Ad populum fallacy, that means R!=U is winning over R=U.
And did you never consider that #2 has dismissed R=U because it is such a baseless bit of totty?
I know you like this idea, but it's simply and utterly without support within the narrative or outside it. None of the themes require Rinoa to BE Ultimecia, and all the evidence is at best circumstantial and often less than such.
