Pilota: a 2D Simulator

Once Ζsolt Βartok's Pilota is completed, it will offer you control of many different types of aircraft in equally diverse missions, ranging from crop dusting and races to rescue operations and bombings. All of that in varied, potentially dangerous conditions and within a big world with islands, airports, oil rigs and many other points of interest.

Even though the game is essentially 2D with a top down view it will have many simulation elements, as according to its creator the proper reading and use of flight instruments will be a requirement. It is still under development so there aren't many more details about it or its date and method of release, but the work displayed so far is certainly showing promise.
