Wild ARMs XF (AKA Wild Arms Crossfire) was released in 2007 for PSP. It was developed by Media.Vision and was localized by XSEED Games in 2008. The European version was localized by 505 games. It's a fantastic and often overlooked SRPG with some awesome music. Definitely one of my favorite games on the PSP. This video shows the first battle and intro movie to the game. It's hard to find a physical copy for PSP, but you can buy it digitally on PSN. According to PSN, it will work on PlayStation Vita.
