This sounds like a really cool concept - and I'm super excited to hear that you're new to game making and wanting to make games that deal with important topics. Welcome!
Please reach out if you need any help or ideas about where to go from here to build your idea! I (or other folks, if they're here) can recommend some easy to use game engines and tools, depending on what sort of game you want to make and what aspects (like writing, art, code, sound/audio, design) you are skilled in / keen to try out.
Good luck!!
