Start a new game you've never tried, theres so many hidden gems on 3ds. take it with you, instead of scrolling on your phone take out your 3ds flip it back open and immediately resume a game even if your just playing for a few minutes.

Download the Virtual Boy emulator Red Viper and play the Wario Land game. It supports custom colours and palettes now!

Download games you want and emulators there are also many cool games that have ports ive been playing fnaf a lot lately on my 3ds you could also mod games and use cheats or just watch youtube there is fourthtube where you can watch youtube hope this helps :3
