This is a game which I started when I was 16-17 for the school. Uses DirectX 8 and Visual Basic. A year later I started a C++ DirectX 9 port, but I abandoned it because the code wasn’t mature enough, and I was more interested in other things.
The original documentation, more like a report actually, for the project can be found here (in Catalan): Tàrraco: Creació d'un joc d'ordinador (33MB PDF)
A demo is available to download (version 0.3):
