Thrillville: Off the Rails  (Sony PSP)

Thrillville: Off the Rails amps up the gameplay with some of the most outlandish roller-coaster concepts ever imagined, as well as new ways to talk to park guests and a new array of carnival games.

Off the Rails lives up to its name with 20 death-defying rides so outrageous, they inspire the same word from every park visitor who sees them: "WHOA!" Players build these incredible "WHOA Coasters" to leap from one track to another, launch through the air like cannonballs, blast through a burning rings of fire and more.

A new lighthearted story ties together more than 100 missions, complete with 34 playable multiplayer theme-park games and social interaction with park guests that's better than ever. The in-depth conversations both advance the plot and suggest better ways to manage the park. But is every guest to be trusted?...
