Shin Megami Tensei: Persona 3 FES is the second version of Persona 3 and it’s the only release with an epilogue that explains what happened to the silent protagonist. The extra episode called The Answer is a straight dungeon crawl where Aigis is the main character in a new storyline where the SEES members are trapped in a time loop. Aigis’ persona morphs into Orpheus and she gains the wildcard, which lets her change personas.
The Journey, the main storyline, has some additions too. You can take Koromaru for walks at night and some of the other Social Links have been changed from Persona 3.
If you missed playing Persona 3 FES when it came out for PlayStation 2 in 2008 you can get it as a PlayStation 3 download next week. The PS Blogcast announced the PSN re-release, which should cost $9.99 like other downloadable PS2 games.
A tip of the hat and Soma Drop to Lynn for the heads up. Thanks!
