Have you every wanted to make 3D games in Python? Did you wish you had something that was more batteries included than say Pygame? Well I have the tool for you! It's called Panda3D and it's a robust 3d game engine with a nearly 30 year long history! It allows you to cod your game how you wantwith support for 3 physics engines out of the box, multiplayer, a very flexiable rendering system (you don't even need a GPU!), a event and task system, great async support, procedural geometry support, a fast to use GUI system, a terrain system, a fun to use particle system, can be coded in Python and C++, and much much more!
So if you're done with Unity or just looking to try something new I recommend visiting Panda3D's homepage and starting today!
