"Best" is subjective, but Mario Kart DS is universally regarded as a system-defining masterpiece and a top-3 DS title by critics and players.
| Game | Why It Competes |
|---|---|
| The Legend of Zelda: Phantom Hourglass | Touch-only control innovation, brilliant dungeon design. |
| Fire Emblem: Shadow Dragon | Modernized classic SRPG, introduced Casual Mode. |
| Professor Layton and the Curious Village | Puzzle-adventure perfection, charming art/style. |
| Elite Beat Agents | Rhythm gameplay + absurd story, high replayability. |
| Pokémon HeartGold/SoulSilver | Definitive Pokémon experience, Pokéwalker support. |
| Castlevania: Dawn of Sorrow | Metroidvania peak on DS, magical seal system. |
If you love competitive racing, MKDS is #1. If you prefer narrative/puzzle/RPG, others win. All are essential library pieces.
