Look, there are way more harmful ways to spend time than those creative games you mention. It can be even net positive for many, especially compared to more mind numbing activities.

I just hate seeing them in hands of kids who should get development pressures from anything but glowing interactive screens, and generally folks who form addictions very easily (I am simply on the opposite side for whatever reason, when comparing to many peers in various drugs but also general mental habits... but I feel if I fell for it hard enough my defenses would weaken across the board, probably permanently).
