i have come to realise games are bad for me but randy i will ive you some tip:
Anything before FFX involves alot of reading but the gameplay makes up for having to read, believe me i hardly read (i should)
final fantasy 7 among all before and up to final fantasy 9, have a world map and are not so linear compared to final fantasy X and X-2. The world map is like full or towns and places and involves more side quests than FFX breeding chocobos in 7+9 should keep you up for a few days along with alot more. not to mention within the game itself it takes around 100 hours maybe more if you want to get all secrets and stuff
the graphics in lower numbered final fantasies are worse, as expected so you will have to bear with it if you don't like the graphics then there is no point in you playing if you don't have patience.
final fantasy 1, 2, 3, 4, 5, 6, 7, 8, 9 are all on the psx or the ps one but it might not be possible to find all of them as many weren't brought out in many places and they arn't as popular in the lower numbers in game shops because most of the population of people who have consoles buy games because they're new, have great graphics, and be able to shoot things.
you might want to keep those things in mind and keep playing
