Yeah I sort of know how you feel, I'm fourteen too and I have 2 v1s, 1 v2, 2 v3s, 1 v4, 1 mini, and the star of my collection my angelgotchi. I also have alot of accesrories for them especially my angel. Some people know me as "tamagotchi chick" sometimes I feel a little old for them, but I don't care I love them all!!!!! The only thing is they have to be on pause alot because of all the obligations that come with being older. As long as something isn't interfering with your life, against your morals, or hurting anyone than why not have fun doing it? Besides plenty of adults who play with them, there are even moms on tamatalk, so a 14 year old person seems totally fine to me.
