The detail that caught me off guard: this simulator was built with Claude and runs on Google Maps, meaning the maker is flying FPV over actual places like Berlin, which is the default location. That is a very different starting point from the usual flat terrain sims, and it fits the stated goal of cruising through cities and the Alps.
The project is open source and up on GitHub, which I think is the right call for something this ambitious. It apparently works right away with just a keyboard, and when a controller is detected the controls switch over automatically. That kind of hands-off setup seems smart, since nobody wants to dig through menus before a first flight. The flying controls are said to feel similar to the aircraft controls in GTA V, which gives a decent mental picture for anyone who has played it.
On the hardware side, it works with a TBS Tango 2, which is a real radio people actually fly with. Beyond the flying itself, the filters, the minimap, and the points of interest can all be adjusted, so the view can be tuned rather than taken as fixed. Those seem like the touches that make a sim pleasant to spend time in.
Nothing is finished here, and the maker says so openly. Controller mappings are still being worked on so they can be configured, adjustable speed is under consideration, and feedback is wanted on whether other controllers work and which features are missing. Apple Maps came up too, but without an API that route looks unfeasible for now. An honest list of open ends, and for an early open source sim that seems healthy rather than worrying.
