Bizarre kusoge grindathon. Unlike most Mystery Dungeon games, you keep everything when you leave the dungeon—levels, stat boosts, equipment—and bring everything back in, too. Where Torneko 1 and Shiren 1 were about strategy and risk management, Chocobo 1 is about fusing equipment together over and over again until you have high enough stats to proceed.
Also, while movement is still turn-based, attacking uses a real-time ATB system. If your attack charges faster than an enemy's—and it usually does, especially once you start snorting stat-boost seeds—you can walk up to an enemy, attack them, run away until you've left their aggro range, and repeat until you've defeated them. This works on every nonboss enemy in the game.
