It&#x27;s mostly just Unity3d and lots of elbow grease.<p>I used blender for the 3d objects and animations.<p>I used inkscape and the gimp for a lot of the texture work.<p>I used audacity for a lot of the audio work.<p>I also made my own library for data serialization with generics. It&#x27;s pretty cool because you can have multiple tables with any data type and it&#x27;ll just take care of it for you. I&#x27;d like to make it able to update to and from a server someday. C# really makes it easy though.<p>None of the tech is crazy, but you can make the Sistine chapel with mud and a stick if you poke it long enough.
