If you grew up with the Gameboy, you might have wanted to make games for it when you were a kid. Thanks to the power of the modern internet, this is now something you can really do!
ClassicGB is a simple game maker that allows you to use your own assets (or some readily available under Creative Commons) to design a simple top-down adventure game.
The games built will be very simple in nature, however full source code of games is available, so you can expand these yourself. This could be a great starting point for a personal project, or a Game Jam entry. (Make sure the rules of the jam allow for source code generators, though!)
Best of all, it’s free and always will be!
If this sounds interesting at all to you, head over to game-builder.cpprograms.net to give it a try!
