Open-world games on the PSP demonstrated that expansive environments, exploration, and freedom could exist even on portable hardware. Titles like GTA: Liberty City Stories, Monster Hunter Freedom Unite, and Freedom Wars gave players a sense of scale, adventure, and player choice.

GTA: Liberty City Stories translated the full-scale sandbox experience to the handheld system, offering missions, Ladang78 side activities, and immersive city life.

Cultural impact included exploration strategies, fan-created content, and discussions of hidden secrets, fostering communities passionate about open-world experiences.

In conclusion, PSP open-world games proved that handheld systems could deliver vast, immersive environments, shaping PlayStation’s approach to expansive, freedom-driven gaming experiences.
