I just got an extra 3ds so i can play games with my gf, but she is not a gamer and was STRESSED during mk7. So, any game recommendations that she wont hate immiduetly and we can play together???

I need some help, would it be worth getting a wii u, if i already have the og 3dsXL. I want to try splatoon but i dont know if that justifies getting a whole new console. Tnx for help

Thank you to all the kind people on discord that helped me fix my 3ds :)

Any chil games that i can play only using the trackpad. I want to play some games during class. sys:o3dsXL

Any essential games that i need on my first gen 3ds?
