Here is a nice and handy list of freely available tools for each area of development and advertisement. This list contains both freeware and open-sourced projects.
GIMP - http://www.gimp.org/
Description: This particular image editor was mentioned on the BYONDBwicki several years ago. So, I thought I would give it a nice relist for this wonderfully free alternative to Adobe Photoshop. As was mentioned years ago, it may have a learning curve in regards to the interface. One nice advantage is you can use all sorts of freely available plugins.
Blender - http://www.blender.org/
Description: Excellent 3D modeling tool that can easily be used in place of several very expensive modeling tools. Reason why I list this one is because some game developers have used it for pre-rendered 3D models (a technique found in early 3D games that are still in a 2D environment). Even someone BYOND have used this technique.

Description: Recently discovered that this piece of software went free as of April 2018. Very powerful digital audio workstation for absolutely no charge; the only requirement being you need a Bandlab account and download Bandlab Assistant to acquire it.
Video Recording/Editing/Streaming/Broadcasting Tools:
Open Broadcaster Software - https://obsproject.com/
Description: A very nice program for recording from about any source ranging from programs to desktop screens to even certain capture devices. Another handy feature is being able to stream to websites such as Twitch.tv. One thing about using this great software is there might be a slight learning curve since you must know how to setup bitrates and other settings. Other than that though, it is very handy.
Shotcut - https://shotcut.org/
Description: A freely available non-linear video editing tool that can be useful for screen capture as well as using capturing from external input devices.

Of course, it can also be used for adding effects if desired.
