Why this title? On paper it’s straightforward: another entry in Sega’s prolific Project DIVA rhythm series, built around the synthetic superstar Hatsune Miku and her Vocaloid peers. But on the Vita, F 2nd becomes more than a list of songs and scoring mechanics—it’s an intimate concert experience, the sort you squeeze into small pockets of time: subway commutes, late-night breaks, or flights between cities. The PS Vita’s OLED screen and stereoscopic audio turn each chart into a tiny performance stage, and the touchscreen and rear pad add tactile immediacy to the choreography.
