Just installed Krita on my computer and I love this program. I don't have the money right now to buy photoshop, so this is a great alternative! I've always wanted to do digital paintings and I can do it for FREE! Thanks a lot, Drone!

No problem dude, happy to help
I'll add all these other suggestions today as well so don't think I ignored you guys

I use paint.net, its basically as good as Gimp, but I think gimp might be better.

The game maker resources were really helpful!
I use unity but I can't do crap Code. Starting with basic programs and learning how they do it is how I do it. Thanks.

I do most of my work in Manga studio.

I was surprised to see it wasn't on the list.

It is on the list Jutsu, it's under paid software

most of the artwork is well illustrated

Yo~ Got a new one for you to add Drone!

Made With Mischief
[WIN] and [OSX] compatible

Pretty cheap for an art software; $25.

The difference between the free and paid versions aren't all that much. With the free software you don't get color palettes, a wider variety of presets, PSD export permission, or (the biggest one) the luxury of layers.

After playing around with the free version for a little while, I came to the conclusion that this software would be best used for sketching out ideas, but it has the capability of going further. The pencil tool is fantastic, and the software is pressure-sensitive for tablet users. It also has an "endless canvas", meaning that artists can doodle to their heart's content.

I'd like to throw Godot game engine into the list: [WIN][OSX][NIX]

https://godotengine.org/

It's a free and open-source game engine under the MIT license. It uses its own language, GDscript that is python-like in its nature. It also has a pretty powerful node-based system. It can be used for both 2D and 3D games. Currently since it's in its youth the documentation isn't amazing by any means, but there are a few tutorials there if someone needs direction.
