It's got a stellar soundtrack, a deep and engaging story, and beautiful pixel art that is expressive enough to convey so many emotions. The gameplay is the best in the series, due to a combination of good balancing of enemies/items and reasons to replay dungeons. Additionally, the content tacked on from Time/Darkness is significant, adding more fun game mechanics and story content that feels genuine. The pinnacle of Pokémon games and a guaranteed spot on my top 5 list.
