Types of Software
This list of software tools was assembled by JT Smith and Jeff King from The Game Crafter Official Podcast. In episode 74, they answered a listener request which asked them: "what software tools are useful for pre-production, before getting to The Game Crafter's online process?".
So JT and Jeff came up with a list of useful tools that can assist you in creating your games. If you are a new designer and not familiar with these tools, we suggest that you watch some youtube tutorials for these products so that you can see which of them will work best for you.
