In order to make your own game character, you have to start from scratch and do the most basic of things, such as create a sprite and then draw it.
However, that’s not all!
You can also add text and sound effects, and make use of the color palette, so that your character is unique and different from the rest of the world.
And then you have the game engine.
You could use Unity or Unreal to build your game, but the process is much easier if you’re using a commercial game engine, such a Unity game engine or Unreal Engine.
Now you can create your own video game characters, and if you want to try out making a character in Photoshop, here’s how you do it.
