Well I deffinitly Preffered the JP Points system for learning Abilities Rather than learnign them off Equipment. I prefer Most of the Features from FFT more than FFTA. Only a few things I would say could be added if they made another Tactics.

-More Jobs (you can never get too many really)
-Good Story (always important)
-Multiplayer Ability, Online Capability would make a Final Fantasy Tactics game amazing.


I'd Like to point out that your idea of addign in the races from all the previous games would most likely ruin any chance of a good Story, because its very difficult to explain how 10+ races from many different Worlds and realms of reality end up together. and trying to come up with good backstory would be hard.

Id prefer to see new races, maybey similar but not the same. I liked how they created new races for FFTA that was good, and i liked the large choice of jobs in FFTA also.
