Probably not the best advice considering the current economic situation but you could cut your losses and restart on Steam. Buy the games there and your kids can probably still do what they did on Xbox. You probably already know this but Steam has a Big Picture Mode which makes it more controller friendly and nicer for large TV displays. Keep a keyboard and mouse handy for when things need technical support.
Yes, Nintendo! Please paywall my nostalgia of the very first game console I ever played! Charge me an exorbitant price during an economic crisis to satisfy my childlike need to regress to a time before I understood what money was!
