There is nothing wrong with letting your child play with cloud gaming provided that it is done with wisdom. The concept of cloud gaming is not bad, but there are screen time and age-appropriate games, as well as a safe environment to play. Make sure you establish clear guidelines (time limits, game ratings), of what they are playing and balancing games with homework, sleep and outdoor games. It would also be a good idea to talk about internet safety and the correct conduct in case the games have social/chat features. Cloud gaming under supervision and restrictions can be a playful low-entry method of playing games with one another.
