Mario & Luigi - Partners in Time

Mario & Luigi - Partners in Time follows Mario and Luigi as they time-travel alongside their baby versions, Baby Mario and Baby Luigi, to save Princess Peach from the Shroob alien invasion that has destroyed Toad Town and half the kingdom. The story involves cooperating across two timelines to defeat the invaders and restore peace, with key characters Mario, Luigi, Baby Mario, Baby Luigi, Princess Peach, and Professor E. Gadd. What makes it stand out is its turn-based battle system using DS features for timing-based attacks, item-based special moves, and cooperative play with baby characters. Gameplay includes puzzle-solving, exploration, and multiple modes focused on battle timing and item usage with hammers and Bro Flowers. It is a single-player RPG with strong emphasis on brotherly teamwork across time.
