My DH sneaks away with my DSi all the time!! I think he might play with it more than I do! I keep telling him he needs to get his own, but he says he will not have 3 DS systems in the house (DD7 has one too). He already completed my Professor Layton and the Curious Village game ( I am getting the Diabolical Box for Christmas!)...he loves playing Mario Kart (DD loves playing this with him also)....but we are both most addicted to 7 Wonders of the Ancient World..that game is so addicting!! We also enjoy WordJong which is a great game...kind of like Mahjong, but you have to form words. He was into Brain Age 2 for a while, but prefers the other ones I mentioned. DH prefers his PS2 for Madden Football and golf games...says he needs the big screen for those.
