I always found classic games to be an interesting programming challenge. The first programming language I learned was QBasic and I remember creating a playable "Connect Four" as my final project which was a lot fun. Unfortunately, the source was lost over the years.
Around the same time, I did what any reasonable person would do: made a few enhancements and put it on GitHub for safe keeping to then forget about it until _one day_ when I would call upon it again... [heroic music plays]
