Tuxemon is a free, open source game inspired by monster-fighting RPGs like Pokémon. You explore a world, catch creatures called tuxemon, and battle them against trainers and wild encounters. The whole game is free to play and modify because it's built as open source software. The game works by combining a few straightforward tools. Maps are created using Tiled, a standard map editor, so anyone can design new areas. Game content like creatures, items, and battles are stored as JSON files, which are easy to read and edit without needing special software. Story events and NPC interactions are scripted using a simple custom language that doesn't require compiling code, you just write text instructions. The game itself runs on Python, a beginner-friendly programming language, which means you can tweak mechanics or add features without rebuilding the entire application. Right now the game includes 183 tuxemon creatures to catch, 98 different battle techniques, 221 NPC sprites, and 18 items to collect. It runs on Windows, Mac, Linux, and has experimental Android support. The project is actively developed and welcomes contributors at any skill level, whether you want to design new maps, add creatures, write story content, or fix code. A particularly useful feature for creators is the built-in CLI debugging interface. If you're making your own maps or tweaking game mechanics, you can type commands directly into the terminal to test battles, give yourself items, or check game variables without restarting. This makes the design process much faster. The game supports keyboard, mouse, and gamepad input seamlessly, and it's been translated into several languages. Because everything is modifiable and open source, you can fork it and create your own monster-fighting game with custom creatures and worlds.
