Think i'll invest in another DSi soon, just to be on the safe side (and take advantage of a few Gamestation deals). My DSL literally fell apart on me from overuse not long after 2 years from purchasing it and i wouldn't like my current DSi to do the same. Even if it is a sturdier, higher quality machine i'm still paranoid. The time i wen't without a DS while saving for my DSi were some of the most painful weeks in my life.
How technical is your game?
