here are some nice FF rumors

I love the rumor about Meteo being an enemy you can encounter 
Heh. Just goes to show the amount of stuff people are still spreading about that game, seven years after it’s release. You’d think they’d have something better to do by now (the people who make the rumours, not the site-makers. The sites are cool).
i guess they are like "If i make a real freaky rumor, some morons will believe me >:) )
Or they are just bored,
but the sites are really cool.
I think the most ridiculous rumor of all of the FF7 rumors would probably be the “Cloud’s Level 5 Limit Break”. The site’s still cool shit, though.
I think the Most Ridiculos Rumor is “Meteo is a Monster with Countless HP and 9,999,999,999,999 MP”, but if all the Rumors were true, FF7 would be the best RPG in existence!
Some of my favorite rumors are the totally ridiculous ones…XD
I remember some hilarious FF9 rumor…It was something about Beatrix, I think? But they said that if you do something, {sorry, fuzzy memory ^ ^} Magus from Chrono trigger would appear and take her away, and they would get married. …Wow. Sadly, if I were a few years younger, I probably would’ve fallen for that…XD I used to fall for so many ridiculous vid-game rumors when I was little. __ I remember falling for one that involved leaving the game on for 14 hours or something like that…and then running back and fourth for 2 hours…It was something similar to this, and i actually fell for it…and was left very disappointed. XD
The very last one was pretty hellarious.
My Favourite FF7 Rumor is :
If you beat all the Turks at once (everytime you encounter them), Tseng will show up during
the meeting in Midgar, he would fight you. (They said he is stronger than Ruby Weapon).
If you win the Turks will join you. Then you have to go to Corneos Villa with Elena and
Yuffie, Don Corneo will kidnap them and escape, through a path which leads to the secret
Dungeon EAST CAVERN! Here you would meet Monsters with at least 50,000HP and the
Psycho Weapon which guards Clouds best weapon the Planetcrusher!
Obviously fake but i like it!
i fell for a couple of the “get Zack in your party” rumors.
BTW, did you know that if you use the initial equips, and never ever change weapons, you will get to see an uber 13337 hentai scene with yuffie, tifa, and Aeries ? I SWEAR this is true !!
Well if I want to see FF-Hentai, I use Internet 
The best rumor of FFVII was that you could fight a monster called Cheese Weapon, and if you won you got the Cheese Ring which would allow you to open a deli in Midgar. That wins hands down.
