I use Unity as my game engine to create games and write with C# because it's basically all I know. For 3D graphics and design I use blender and for 2D I usually use adobe illustrator for sprites or photoshop. I'm planning on using Adobe Animate for animation but i'm not into the stuff yet. I use Visual Studio as my IDE because it's default for Unity and is just easy for me. I use Garageband for creating soundtracks and plan on upgrading to something more complex like FLStudio or maybe Logic Pro when I become better at it.
