Better known today as the developer of Skyrim and Fallout, Bethesda once had a well-respected racing game franchise and were deep into development of a licensed Skip Barber Racing title that never released.
Asobo, known today as the Microsoft Flight Simulator developer, created groundbreaking technology for large scale maps that was intended to be used in a high quality rally raid title. It was never released and ended up as FUEL, a post-apocalyptic open-world racing game. What happened?
PC version had two cars, 4 tracks that were secrets and can be found on the CD. Toyota Celica GT4 WRC, Millennium 5 Rallye and four fictional tracks.
Running on Windows 10
Install from CD (I selected not to install DX6 but allowed the Indeo video drivers to install), install the 1.5 patch (needs XP compatibility set to find CMR installation), then run using Rally.exe (using Windows 98/Me compatibility) being patient to the fact that it took a clear 10 seconds for the Rally.exe window to appear in my taskbar. Note that you will not see the intros because you are skipping them by using Rally.exe instead of Game.exe.
