I'm working on an ongoing, much larger scope project to produce a rally sim based on the niche world of Targa Rallying. But as I'm pretty early in game my game development journey, I wanted to try and put together some smaller scope projects focusing on mechanics and shipping finished mini games. So I gave myself a week long sprint to recreate the first few license tests from Gran Turismo 4. I ended up following a bit of a different path but I'm pleased with the finished result and learned A LOT in the process. I plan to make some more mini remakes of titles to really focus on crafting game mechanics and not just producing yet another driving sim.

If you'd like to see what went in to the making of this, there is a full 15 minutes Youtube video.

There are plenty of rough edges with this project, and I might spend some time refining it or it might be the end for this release. My next job is to spend some time working to either refine the existing physics or build something new from scratch.

And if you enjoy any part of this, I would REALLY appreciate a subscription to my Youtube channel as it's tough trying to grow anything from scratch
