Most readers probably don’t know about F.O.G. (short for Full on Games) since they aren’t as active, but they had a sizable fanbase during the Dreamcast days. Missing Parts: The Detective Stories is a three game mystery series and the last title came out two years after Sega stopped supporting the system.
F.O.G. works with Nippon Ichi now who published the PSP game Musou Tourou. The two companies are working together again on Missing Parts: The Detective Stories Complete for PSP. Dengeki PlayStation reports this collection will all include three Dreamcast titles plus extra content.
