9. Nayuta no Kiseki (The Legend of Nayuta: Boundless Trails)

If you love Danganronpa or Zero Escape , this is your holy grail. A student wakes up with no memories, trapped in a school with a giant monitor counting down to "Game Over." It is dark, psychological, and recently received a complete English fan translation. The pixel art and branching narratives hold up beautifully on the PSP’s 4:3 screen.

A fast-paced action hack n' slash that brings characters from 15 different Tales of games into one, including Tales of Xillia . Its combat is deeply satisfying, combining mash-up Musou-style gameplay with the precision of the Tales series' arte system. 2.

A parody of WWII history where nations are represented by anime girls (and later, bishounen boys). It is a tactical RPG like Advance Wars but with a ridiculous sense of humor. The "++" version adds new units and a harder difficulty. It is an easy pickup-and-play if you enjoy tactical gameplay over reading story.
