We all lean when playing racing games and sit up in our seats when jumping in action games, but so far most PSP games have stoutly ignored all that nonsense. The TiltFX from Codejunkies might finally make those uppity consoles a little more responsive with a "G Sensor" -- a three-axis MEMS gyro that clips onto the lower-left of a PSP 1000, 2000, or 3000-series console. (Sorry, Goers, left out again.) Once plugged in you can simply tilt the console in the direction you want your character to go, something that we could definitely see enhancing the experience of games like Archer McLean's Mercury or or Loco Roco. And, for just £14.99/$19.99, it's certainly a better value than some other PSP accessories we've sampled in the past. Video demonstration after the break.
