Just found another PS game made with RPG Maker XP. This is part 1/3, part 1 is completed and fully playable. Haven't tried it myself, I'm downloading it right now, but figured I would share it here. I'll probably only get to play for less than an hour or so today, so I'll post a little more on another day. Definitely awesome that people are coming out with more PS related stuff!
Seems like it is a afterword kinda game to PS IV, dealing with the aftermath of the story, going on hunter missions and etc. More details and some pictures can be found below, along with the download link.
