||An early cheat in the series gives you an advantage to owning multiple games. If you have Clash of Ninja data saved on your memory card and start Clash of Ninja 2 for the first time, you will receive a shop bonus of 10,000. Having Clash of Ninja 2 on the memory card and starting Gekitō Ninja Taisen 3 will give you the same bonus for the second game, but 10,000 more if you have data from the first on your memory card as well. However, the cheat stops with 4, as you don't get a bonus for having 3 saved on the memory card since there is no shop.
