What game for the Ds do you guys think I should buy I just bought a Ds yesterday

Im going on vaction tomorrow and I need a game that will last me a long time maybe a role playing game what do u guys hink?

depends what you like. New Super Mario Bros/Yoshi Island/Mario vs DK 2 March of the minis are all good platformers that will probably take you a while to get through.

Big Brain Academy has lots of replay value if you like that sort of thing.

Some of the Pokemon games last a far while if my son is anything to go by.

Puzzle Quest is supposed to be very good.
