Looking at how Fallout 3 runs on Windows 10 and if it is compatible with Microsoft's new OS.
As an older title (and a non-Steam copy installed from DVD) this title could have been challenging for Windows 10, however pleasingly it detected the game as soon as the DVD was entered and provided a download for the Games For Windows Live client, as the version included on the DVD would not work with Windows 10 (or 8).
Once this was installed and the game was patched it ran correctly.
