Ah Grandia, one of the biggest gems in the Saturn and PSX lineups. Also one of my favourite games of all time, it's combat system completely blew me away when I played it.
It seemed simple at first, but it was rather complex and in-depth, especially when you add in the different Eggs to learn different types of magic, the rather large span of abilities that each character could learn (and how it would increase given some story events) and how each one had a different effect on the action bar.
Not much credit is given to it and Grandia 2, mostly because the series fell into a complete mess with Xtreme and 3 (sadly).
