Neither iPod we own is capable of actually playing Song Summoner, so we had to borrow a peek at someone else's. Like a Monster Rancher, an Audiosurf, or even a Vib Ribbon, Song Summoner can transform your music collection into gameplay. The metaphor here is a tactical game, and the product is (startlingly enough) from Square-Enix, a company with a strong pedigree in the genre. I'm not certain that the clickwheel is a strong contender ergonomically for this kind of experience, but when they dish up the inevitable iPhone and iPod Touch versions I'll have reason to celebrate.
