Yeah that’s why I let my kid do specific chores to earn money for mtx. So he has his dripfeed to support whatever costumes or other mtx he sees - but not enough to get truly addicted. Plus I have been very forward with him that the money he spends on mtx is literally worthless the moment he buys it - so I give him normal allowance at a higher rate than his small mtx earnings. My goal is to balance it out so he can have non-standard skins and not feel made fun of for it, but also not grow psychologically dependent on them like some kids.
