Back in January of last year, Practical Intelligence Quotient 1 (PQ1) was released on the PlayStation Portable (PSP). Video game developer Nowproduction Inc. and publisher D3Publisher of America (D3PA) believe that the game was popular enough to merit a sequel.

So come summer of 2007, fans will be able to get their hands on Practical Intelligence Quotient 2 (PQ2). To those not quite familiar with the game, the PQ series uses a measuring system that was created with the help of Kyoto University Professor Masuo Koyasu. D3PA Vice President for Marketing Alison Quirion is excited about the new project.

PQ1 resonated exceptionally well with gamers and we look forward to offering PSP system owners the second edition to the best-selling brain game on the PSP system. PQ2 will offer a compelling and rewarding gameplay session that translates well to portable, on-the-go gaming.

In PQ2, players will be able to create their own puzzles and share these with other PSP users via the system's game share mode or utilize infrastructure mode. Also, Practical Intelligence Quotient 2 will promote flexibility among players as it gives them the option of playing what puzzle they want to finish first.

A preliminary PQ score can be obtained by playing around 10 minutes. To see if the video game has helped improve your intelligence quotient, playing the full puzzle set including 10 unlockable ones will give you your full PQ score.
