As someone in the same position as you I would say it's more like winning the lottery. The game environment is filled with games so adding another one to the pile won't do much. I think making a video game is a great idea. Having myself coded a web browser game in JS its a lot easier now with all the tools and game engines available then it was 7 years ago. I would say that you should go for it. Build your game and release it. The market for crafting survival/ slice of life/ crafting games is huge and you definitely could make the next game to take the world by storm. I would recommend not quitting your day job though, unless you find a way to cover life expenses and build the game.
