Bathing Simulator
I came up with the concept of a video game while showering yesterday called "Bathing Simulator" where the goal of the game was to successfully bathe yourself in a forest river, but while that goal seems simple it actually ends up requiring you to overcome a great deal of obstacles which makes the gameplay much wider in scope than you would expect from something called "Bathing Simulator". So at first you would find that the river, though the water was clear, would occasionally have debris flow through it that would make it unsafe to bathe in, like large pieces of driftwood, and you'd have to go upriver and clear debris, but then when you returned, you'd find now that animals were shitting in the river, and you'd have to go upriver and discover bears shitting in the river, so you'd have to use the debris you cleared and various other resources in the forest to create weapons and kill the bear, but then you would find that all of this work has made you dirtier than just water can clean you from, and so you have to collect firewood and create some kind of pottery vessel to render the bear fat in and then mix it with the wood ash to make soap and then finally you could use that soap to bathe. And so I imagined there would be tutorials online like "Bathing Simulator tutorial: how to most effectively kill bears" and anyone who had no context on the game would be completely confused by a title like that.
