On my first playthrough of FFVII, I used a walkthrough for the whole thing because I had no clue what to do.

I've never gotten to play V even though I really want to; it and III are the only non-MMO numbered games I don't have. I'm thinking of waiting until they do a remake for 3DS, but I'm not sure if that'll happen.

I really liked what I played of FFXIII, greatly enjoyed the music, graphics, character designs, voice acting, and especially the battle system, but I only got up to Lindblum because my PS3 crapped out and has trouble reading dual-layer discs. :/
