I suggest animal crossing wild world. my mother, who is 58 and never plays games is addicted to this. being so I had to buy for her, her very own DS just so i could have mine back
its a simple and easy game to learn, you play as a little boy or girl. you get a home in a town full of animals that talk and move like people. you get to go fishing, bug catching, digging for fossils, which all can be sold to buy furniture for your new home

you can have a simple home with white furntiure, or perhaps you like a pirate theme? even mushrooms! unless your more into the season, a snow man theme or halloween.
also the time on this game goes as our time. if its new years in our time, it will be on the game. if you get on at 2 in the morning, its going to be 2 in the morning there also.
its a lot of fun and addicting

no violence at all in this (unless you count the bee stings if you shake a wrong tree)
also another game i got is mario DS. its a remake of the older mario from N64. its like a classic mario, but better grahics.
both of these games are a east 30 dollars or less. if you have one near you, cheak at a EB game store.
