This seems to be slightly better than the Game Deal.
Choose from one of the four games,
Super Mario 3D Land
The Legend of Zelda: Ocarina of Time 3D
Theatrhythm: Final Fantasy
Resident Evil: Revelations
Super Mario 3D Land is the best among the 4 in my opinion.
Do not forget to add a charger if you need one (if you do not have any old model of DS that is).
It might be better to go for the 10 in 1 accessory pack (which includes an USB cable charger and a car charger) than to buy charger on its own.
