Bottom line: Golden Sun is the best handheld RPG ever, and one of the greatest of all time.
Golden Sun has everything good about this game. The gameplay and story is just like a movie, and it draws you in much like a great movie, novel, or RPG (which this is.) The graphics are some of the best on the GBA, despite this being one of the earliest GBA releases, and the battle animation will leave you awe-struck. The in-game music does NOT grate on you like many handheld games, but actually enhances the game and also sounds like a movie (soundtrack) and the sound effects are brilliant.
Probably the only thing wrong about this game is that it confuses you many times on what exactly to do, but hey, it's supposed to make you use your head! So nothing's really wrong with it. That's right! Flawless!
The Bottom Line
Golden Sun is one of those games you absolutely must have if you own a GBA. It's also one of those rare and wonderful games that sell systems. It's a deep, highly satisfying role-playing game that ranks as one of the Top 5 RPG's of all-time, and if it's not among your collection, then you're missing out, BIG TIME.
