4.
Brave Fencer Musashi - This action-adventure RPG from the PS1 era has a fun blend of swordplay, platforming, and adventure elements. You play as a young warrior tasked with saving the
kingdom from an evil corporation. The combination of humor, colorful characters, and engaging gameplay makes it a unique experience that holds up well over time.
5.
Sakura Taisen (Sakura Wars) - Often regarded as a hidden gem, this hybrid title blends adventure and tactical RPG elements.
