This game is the first of a trilogy. Basically, on the Turbo, we got Legend of Heroes 1 & 2, which, together are considered Dragon Slayer 6. Then later they did the Gahgarv Trilogy, which is Legend of Heroes 3-White Witch, Legend of Heroes 4-Tears of Vermillion, & Legend of Heroes 5-Cagesong of the Ocean(which were all "remade" by Bandai for PSP, & released Stateside out of order). This game is part 1 of Legend of Heroes 6-Trails in the Sky, which is also a trilogy(& all 3 are slated to be brought over by Xseed).
LOH 6 however was brought to the PSP by Falcom themselves, rather then Bandai, & are supposed to be simply fantastic, & very deep. These 3 games are probably one of, if not the biggest releases Xseed has ever taken on, atleast in terms of the sheer amount of text involved to translate, not to mention it being a trilogy in general. The next game is being released on 2 UMD's because of how huge it is!
Needless to say, I'm very excited about this coming over here!!
