I am a solo developer hoping to make people happy. I mainly focus on puzzle games, horror games and adventure games but you can suggest other game ideas for me. It helps me a lot with getting good game ideas by using other ideas. My first game is called Luminescence. Currently it is in early access and is around 60% done. As a developer one of the most important things is the idea, the idea is the start and end. When you do not have an idea, you do not have a game.
