I have been playing Hero Kids[0] with my 4yo son since he was 3.5 and we have a blast every session. the best part of it, is how flexible are the rules and you can relax them as much as you want for smaller kids. I can def see how the approach in the article could make complex games more accesible to kids. As soon as my son is a bit bigger I’ll try this for sure.
