I may not be best person to comment as actually I don't like any of the Grand Theft Auto games either (that I've tried) and I don't really intend to get Grand Theft Auto IV - well, I'll wait until I can get it for $5 or less which won't be a problem since GTA broke the record for highest selling first week sales of any entertainment item in history (that is music, movies, video games).
Six million copies sold in the first week. I'm sure tons of those will show up in used bargain bins eventually. Grand Theft Auto is supposed to be violent and shocking, and I get that - that's why it sells.
Certain games nowadays do look very realistic and are too violent for me as I'm not into violent games (stuff like Max Payne) - but I don't really see that so much on the

DS. Of all the newer game systemss out there, the DS seems to me to be the tamest and friendly to play. If she was expressing shock over a game like Grand Theft Auto IV, Manhunt 2, or Army of Two, okay I could see more where she's coming from, but Rosie Millard is calling games like Brain Trainer and Fifa 08 the source of her children's bad behavior.
Buying a single DS for four small children and the family is like buying a single console with only one controller or at dinnertime, letting them all share a fork. Duh, of course that's not going to work and they will be arguing over it.
