I personally think the tattoo thing is a coincidence. They probably gave Ultimecia tattoos to make her look evil, and they probably gave Zell tattoos to a) make him look cool and b) because they thought getting tattoos was a very Zell thing to do.
Probably, but I cannot imagine what was Enix thinking when they added his tattoos, surely they could be confusing? Enix has stated that Zell's tattoo is nothing special, anyways.

2. Time was never compressed fully, if it had been it would've been game over.
Several things? Not exactly. The guide only stated one thing (life span) which significantly kills the R=U theory but that's still not enough because they didn't explain more and they don't want to. Why? You tell me.
R=U is not heavily relied on the 'Oh no, their life span is still the same as a human' fact, anyways.

2) The FF8 game portrayed the story of FF8. The only thing it would have been game over is that if you fail the game. Is there proof that the world of FF8 wasn't fully compressed? There are so many things that have never displayed in the game, so yeah.

((( this is the important bit! )))
In the compressed world, Squall travelled to the past; saw his little self being and told Matron whatever the hell he wanted to say (the garden ideas, etc).
So listen, if voices (like that example of what he said to Matron) and figures (like that example of Squall seeing his little self being and Matron) can affect a timeline from between the past and the future. Then what about other things like merging? e.g. merging powers or bodies. This can boost significance to the Rinoa and Ultimecia relationship. Will that happen after the game? Maybe.

I'm still not sure about the human life span thing though, I can't believe in saying this but Albert Einstein once said that if you start travelling via a spaceship AT a very fast light speed from Earth to millions of light away and then go back to Earth, your life span may BE STILL the same as normal BUT the people left on the Earth have aged faster (dramatically) than you have.
Ultimecia has powers like this. When she starts a Time Compression, does it change the light speed? Probably, but will Ultimecia be affected by the changed speed? No? This means that Ultimecia has aged just like a normal person and went through so many generations due to her powers (time travel). What I'm saying is that the human life span concept isn't important in such situations, because with Ultimecia power, you will age 1 year older and the world will age like 1,000 years older.
