Oh boy, am I so glad that I read this post and to know that I am not alone with the DS fanatic children. I was also very determined to keep the whole video game stuff out of the house and boy I won out until about 2 months ago....my husband had a DS that he used at work to help destress him and DS6 started to watch him play and then pretty much stole the DS from my hubby....so he got his own DS for his birthday. What is it with him wanting to go from start to finish on all of his games???? He completed Phineas and Ferb from start to finish in like a week. With his perfectionist streak, I will hear him throwing a fit when he messes up and then he will actually work forever completing a difficult level, only to wipe it out and start again! We have also begun to limit his time on the DS and i love the whole timer thing!
