I think that making a game to inform individuals about how to properly conduct first aid is an amazing idea! If you can find a way to make it both fun, informative, and concise it definitely would be a very impactful gameplay experience. I also like how you mentioned knowing the laws in regard to assisting someone in need of medical attention as it plays a large part in both an individual's willingness to help, but allows for a quicker response time for civilian assistance.
