Is it worth playing? Yes, absolutely. Zero no Kiseki is a masterpiece of world-building. It bridges the gap between the Trails in the Sky trilogy and the Cold Steel tetralogy. If you have played those, missing Zero (and its sequel Azure) leaves massive plot holes regarding the Ouroboros society and the state of the world.
Pros:

These early "English Patched" PSP ISOs were rough—often having untranslated NPC dialogue or buggy text boxes. Yet, they were the only way to play Zero on original hardware (PSP, PS Vita, or PPSSPP emulator) for years.
