Sega Rally Revo for Sony PlayStation Portable (PSP)
A handheld version of SEGA's revival of the dirty and wild SEGA Rally
franchise, this PSP version features 34 different cars and 16 tracks
that span six different environments. Multiplayer offers play over the
Internet via Infrastructure support for up to four players, and gamers
can also play locally -- you can even use one game for two players via
the PSP's Game Sharing feature!
