About suggestions: There are a million tools out there, but this list is intended to be readable and useful, rather than an encyclopedia of ALL the software in the world. Don’t get annoyed if an obscure tool is not added.

Here’s the list of resources from this year’s Sponsors, along with some other stuff.

Here's a smaller list of tiny game making tools, perfect for beginners!

Note: Resources listed here are generally free, though some have paid plans for extra features.
