Materia was prolly the easiest, most enjoyable, and fun to use system imo. Junctioning was just annoying. Honestly, you find a monster with Flare, then you spend the next 20 minutes spamming Draw to get all 3 characters to 100? Yeah thats fun :rolleyes2

FFVI was fine, learning your spells through magicite (prolly 2nd best)

FFIX was a similar system to that and I liked it also

Stupid systems:
FFIV (pure leveling for skills sux.. dont get me wrong tho, the game rocked),
FFII (Realistically it makes sense. Use magic, you become better at it. The original release it was bulky, time consuming, and easily exploited as well)
FFVIII (Spamming Draw =| fun)
FFX (I'm sorry, grid system was ok for first half of game, but then when everyone started overlapping.. it was just a "Oh boy heres another 200hp to add onto my already 10k+ total".)


*sigh*, I also loved FFTactics for some reason. Build up Job Points, and spend them to learn a new ability for your job, in no particular order i.e. if I wanted to learn Flare for my Black Mage before Dorter Trade City, I'm free to do it (tho thats not very realistic, its a choice!)
