Jam Sessions DS review at Destructoid.

"At the tender age of 13, I picked up a guitar for the first time. A cheap acoustic number with strings whose gauge are illegal in most parts of Eastern Europe, the tips of my fingers nearly bled as I forced my digits into unnatural positions. Hours, days, and weeks of practice later, I could play just about any song in Nirvana's catalog.

While my dreams of being a rock star never truly paid off as a result of endless practicing, it did help me out with the ladies as I got older. Ubisoft's non-game acoustic guitar simulator/tool for the Nintendo DS, Jam Sessions, might not be the key to success with the opposite sex, but it may be the easiest way for someone to pick up and "play" the guitar."
