While Persona 3 Portable isn't quite an exact port of the original PS2 RPG, it retains most of the gameplay of the earlier release. This overview video provided by Atlus is a perfect way of understanding the mechanics of the original game, from attending school, to making friends, and eventually fighting with your Personas. Anyone that's played the original will find themselves in very familiar turf here; however, Atlus plans on releasing a follow-up video, chronicling everything new in P3P some time soon.
