During the early days of the Zune I built a colletion of Arcade Games using .NET and XNA. This is the first set of games I ever released to the public. It was a pretty exciting time.
To actually run the games, every user would have to manually install Visual Studio Express and download the XNA libraries. Even with those limitations, I still had 1000’s of people download and play my games.
