*Edit* If I was in an FF8 story line I would go back in time and beat the crap out of myself for dating my first gf, gawd I was such an idiot, I COULD CHANGE ALL THAT!!!
Same with terminator and other time travel media. However I'd just go back in time and knock up my first gf. Probably it would teach my younger self some responsibility.
the problem with applying "time travel" or mixing past/present/future as a reachable place in any game/movie/anime or any other tv series etc that may have had such a plot, is that it's full of more holes than swizz cheese. I honestly never bothered to question it, I looked at it for what it was and sure maybe I tried to make some sense of it but never could be bothered to over think it because of topics like this.
It's been said already, there's people getting flamed on other forums for messages about squall being dead, rinoa being ultimecia etc. oh btw I rinoa is not ultimecia, square enix themselves put that to rest when serious speculation was rising and before that I gotta be honest even I thought that was true, but alas, it is not. Squall is not dead, if he was the entire game after disc 1 would be a dream.... if i'm not mistaken squall woke up in bed after disc 1 supposed death, perhaps he was dreaming that he died! yet another possibility, geezus, it's endless >.> *goes back to drinking and stops trying to apply logic to "fantasy" games*
