Super Chinese World 2 is the sequel to Culture Brain's Super Ninja Boy. Like its predecessor, it's a brawler/RPG hybrid where you walk around an open world, talking to people, buying items, and solving quests. When you engage in combat, the game becomes a brawler where you gain experience at the end of the battle and level up.
This game is of course part of the Super Chinese series, which spans over 10 games across Game Boy, NES, and SNES.
This game was going to be localized as Galactic Defender but it got cancelled.
Super Chinese World 2 is a step up from the first game due to adding some extra characters and techniques. However, its combat is still disappointingly shallow and slow-paced. That being said, the graphics are a huge improvement over the original and the music is slightly better as well. Of course, it's not translated so good luck beating it.
