This is just a bunch of random ideas that I thought about. You can use them just with some credit. 1-Rain; It was some game that I remember watching about two kids that were like ghosts that could only be seen in the rain or if they stepped into mud puddles, and there were other ghost creatures that were chasing/hunting them. 2-Sketched; Maybe a game, maybe an animation, but there was a megacity of Sticktopia (I know, real creative) an that something was happening where stickmen were turning into sketch-monsters that spread to other regular stickmen, and there was only a few survivors trying to escape the city center. 3-Dont go Nuclear; A simulation game where you would basically run a power plant and keep the output above a certain level while not going nuclear. 4-A more interactive real world-ish simulation. idk, like something like base building that's really in depth 5-Minitopia, a city builder that instead of making people do jobs, they have to learn and choose themselves 6-In-depth gun builder 7-cool parkour like dying light or something
