Seiken Densetsu 3 - (secret of Mana 2 w/ english patch)
I consider this this the best JRPG of all time, everything is great and its one of the only JRPGs that has massive replay value.
Ys Series; These are great games with an arcade action feel to it, Ys 1,2, and 4 are more classic and very much RPG-like, Ys 3 was an experimental 2D platformer, 5,6,3(remake), and 0 Are similar to Zelda, except there is a demand of Challenge. 7 and 4 (remake) are similar to the previous but implements a Party system which works really well.
The PSP, this is a JRPG machine, and most of the games are really good, its an easy way to experience Final Fantasy 1-9, almost all the Ys games, Star Ocean, Phantasy Star, and God Eater plus many more.
