+After re-playing GTA:SA, and also because of my general interest in old games, I one day searched GitHub for projects related to GTA San Andreas.
+This led me to the [San Andreas Unity project](https://github.com/in0finite/SanAndreasUnity).
+I was very much interested in Quadcopters at the time, and I was also looking to gain some experience in working with Unity.
+So I decided to attempt and [combine](https://github.com/xythobuz/SanAndreasUnity/tree/sim) the two topics.
+
+Here is a video of the simulator in action.

+
+The "physics" "simulation" in my code is not working very well.
+To reach the state that can be seen in the video above already took a lot of tweaking, and the result is obviously not optimal yet.
+
+Together with my [SerialGamepad project](http://localhost:8080/2015_12_20_serialgamepad.html) I was even able to fly in the SA:Unity sim with my usual quadcopter transmitter.
+
+But my curiosity was satisfied at this point and I had no more interest in working on it further.
+
+Here are some screenshots of San Andreas Unity without my quadcopter modifications.

+My fork of SanAndreasUnity can be found [on GitHub](https://github.com/xythobuz/SanAndreasUnity), the simulator experiments are [in the 'sim' branch](https://github.com/xythobuz/SanAndreasUnity/tree/sim).
