Probably most of them, hah. I didn't use GFs much ever, really. Got them all the second time around for completeness sake, but still never found much use for GFs.

Well using the actual GFs was never really an issue (exceptions were Jumbo Cactuar and Doomtrain imo) was never really the point.

I think it was all for their passive abilities you know?

Funny thing is, I never completed my first file. I got bored by disc 3 and started over. I know I didn't have all of them so far though. I missed siren and carbuncle but by the time I decided to finish the game I got them all.

i didn't miss a single GF in my first file (I went draw crazy that file to get 100 everyrhing, so i was able to also draw out some GFs from the bosses.)

First time through I missed Carbuncle and Cerberus, maybe a couple of others toward the end. I went back and got the strong ones (Tonberry, Eden, etc.) in Disc 4. It's easy to miss Carbuncle, but I don't have much of an excuse for Cerberus. It was too hard! And I was in a rush to get out of Galbadia.

I went back and took a look at my old save file from 4 years ago and the only one I'm missing is Doomtrain; I have all the rest.

Wow, the first time I played this was back in 1999 when it first came out and I think I remember missing Carbuncle, Doomtrain & Tonberry King.

However, the second time through I did get them all.

I didnt miss any of the ones where all you had to do was draw it from a boss. I did miss Doomtrain and the other secret secret side mission ones though

On my first time playing FFVIII I missed out on Doomtrain and Eden, just because I didn't know how to get those at the time.
