FF1- 3 (i think)
2 - 2
3 - 5 (unlike 5's system, i liked this one)
4 - 3
5 - 1 (the job system ruined the replay value)
6 - 3
7 - 8 (it was the only one i had access to for about a year or two)
8 - 3
9 - 2
10 - 2
X-II - 1
Chrono Trigger - 12 (technically not from start to 'finish'...i can beat it in about an hour with marle+crono at the start...probably less than an hour)
Crono Cross - 0. I hated it.

I'd add more but that is quite enough.
