I enjoy the many ways you look into this concept. It's always a great idea to share information of how first aid works here in Canada. In other words, I like how you are looking into the Good Samaritan laws for a game like this one. I never knew much about this until I read it up on your post. Not all of us are willing to offer immediate medical attention, therefore, it could really affect the lives of many people across Canada. This also allows civilian assistance to react as quickly as possible. Given you have experience with first aid, I'm curious of how you can put these first aid factors into a game. Many people's lives could be at risk if we refuse to come to their aid so perhaps you could make a game of where you solve some puzzles to make a kind of life saving game which would perfectly align with your topic. In the process, this would also help people learn the ways of basic life saving problems in an engaging manner and benefit from this a lot.
