Blender - Free 3D Modeling Software (Free)
I highly recommend checking out Blender if you want to create 3D models. I use Blender on a daily basis to create all of the 3D models on this site.
"Blender is the free and open source 3D creation suite. It supports the entirety of the 3D pipeline—modeling, rigging, animation, simulation, rendering, compositing and motion tracking, video editing and 2D animation pipeline." - Blender
Unity - Game Development Software (Free)
Unity is my prefered game development software because of its intuitive interface, excellent documentation, and its ability to export the game to many platforms. Click on the link below to get started today. Also, check out my YouTube video that shows you how to quickly install Unity, https://youtu.be/IzIJetbwuks.

Visual Studio Code - Code Editor (Free)
Visual Studio Code is the code editor that I use for almost all of my projects. I've tried many other code editors but this is by far my favorite.
Audacity - Audio Recorder & Editor (Free)
If you want audio software that is excellent at recording and editing audio with a simple interface, then Audacity is the right choice. I use this software to record and edit all of my tutorial video voiceovers and game audio clips. Side note, Audacity also has great noise reduction tools built into the software which is very helpful for people with entry level microphones.
"Audacity is an easy-to-use, multi-track audio editor and recorder for Windows, macOS, GNU/Linux and other operating systems. Developed by a group of volunteers as open source." - Audacity
