In my third time playing FF8 I am attempting to get a complete card collection, does anybody out there know this....Can i gain back any cards that i need to lose to get others For Example..to get Rinoa I need to lose Ifrit to Rinoa's father, is there any way to get Ifrit back?...this goes for other cards too.

Man i love FF8 :)

If you lose Ifrit to Carraway and then talk to him about cards, he will tell you he lost the card to Martine in FH a few days ago (even if you don't leave the room haha)
You can normally play the person for the cards that you lost to them throughout all the discs.
I lost my sacred and minotaur to some guy in Balamb and then a disc later, I challenged him and won them both back!

Thanks that's a great help..These so called Official Guides are SH1T..I played FF8 all the way through once without guide then bought it to pick up on stuff that i missed out on and here i am finding out that there are still things that are not in the guide...Also on a side note..I did find that in the guide to FFX there was ALOT of errors!!! nevermind they still got my damn cash..Thanks for the help on the old Triad game :)

What about the cards you lose to the Card queen can you play her back to get them?..Like near the escape Pod later on and all that?

Yes, look for a card FAQ or a sidequest FAQ, it will tell you all the places your card will show up again after losing them to the card queen.
Here is a good link for guides

The guy in Balamb Town who can change the rules how often can he change them back to normal.....the first time i played the game..I got him to change them back, and then...the rules got very mixed for me AGAIN..LOL..and i wanted to change them back..the first time was DISK 2...he was there..the second time...was Disk 3..and he was no where to be seen

The fisherman in Balamb appears randomly, he never disappears permanently. Just leave Balamb and re-enter until he comes back.

when your on the qoc quest she gives all the cards you lose to her to her son in dollet in the painters house apart from the first lvl 8+ card which she keeps

i never really got into to triple triad so next time i play im gonna have a go, is there ant easier ones to begin with to get me into the game?
