I-- 3-5 times
II-- once
III-- I think three times.
IV-- no idea, but probably a dozen or more.
V-- 3-4 times
VI-- 6-9 times, I'm guessing.
VII-- twice. The second time just to make sure I was being fair.
VIII-- once
IX-- twice.
X-- just up to the point that I realized I'd need a much better computer for the game to emulate in more than slow motion =( [didn't take long to figure that out].

Tactics-- once
Tactics Advance-- once
MQ-- 6-9, I'm guessing (I was a kid. The game is fun. Not a mind-blowing RPG, but fun enough for a kid).
