Was Jade Cocoon any guy? Buybacks had a copy but they like, closed down last week.
Of the games you got, I think Grandia 1 is fantastic and like it a lot more than 2. I never got very far in Vagrant Story but it seems cool. Parasite Eve 1 plays kind of like a simplified (in a good way) Vagrant Story set in the modern era.
Xenogears is odd. The gameplay isn't particularly... good, and the battle system is based around this elaborate combo system which adds absolutely nothing to the game. The story also is... a thing. But I definitely would recommend playing it, because it is important.
Imma throw out some recommends for:
- SaGa Frontier
- Brave Fencer Musashi
- Shadow Tower. Or anything King's Field, really, tho I think Shadow Tower is the best.
- Wild Arms 1 and 2.
- Legend of Mana (It's really easy, but has like, my favorite setting and story from any Square game).
- Granstream Saga
- Guardian's Crusade
- Star Ocean 2
Oh and Valkyrie Profile but that probably causes a million dollars.
