I actually liked the gil system of FFXII, looting was fun! If time consuming, though, but it felt natural and searching for the creatures with best loot was..fun too I guess. The bazaar could've been better though, there were no way to see what you had actualy sold and such...

FFVII is easy to get money in when you get to a certain point in the game where you can find the head hunter enemies, and quickly master your ALL materia, and then sell it for a VERY high price. Correct me if I'm remembering it incorrectly.
