Knights Field series. I never could get into them back in the day, but I've been on a retro kick with my Anbernic and got sucked into them. Ended up putting 20 hours so far into the English translation of the first Japanese KF.
Also, Vagrant Story. Pretty much same scenario where I rented it back in the day and bounced off the combat for not making any sense to me. Tried it recently and really dig it. The combat system is really quite clever once you understand it.
