In its E3 press conference today, Sony briefly showed footage of Titan Studios's (formerly Darkstar Industries) team-based strategy game Fat Princess running on a PSP, along with several other titles for the handheld.

Unfortunately, Sony, which is publishing the downloadable game through PlayStation Network this month, didn't disclose whether the PSP version will include any unique features or when it will release. The company, however, did reveal another interesting title for the system in its sizzle reveal, Echochrono, a sequel to Japan Studio's odd puzzler Echochrome.
