Lumberyard is Amazon’s very own video game engine. Based off of Crytek’s famous CryEngine, the engine can be used to develop games for both PC and console. The biggest feature about the engine is that it is completely free. No seat fees, subscription fees, or requirements to share revenue from production.
The only time developers will need to pay any sort of cost, will be when they decide to make use of the engine’s integration with Amazon’s Web Service for multiplayer. The engine also has great Twitch integration:
With Amazon Lumberyard’s Twitch ChatPlay, you can use a drag-and-drop visual scripting interface to create gameplay features in as little as minutes that let Twitch viewers use chat to directly impact the game they are watching in real-time. And, the Twitch JoinIn feature within Amazon Lumberyard helps you build games that let Twitch broadcasters to instantly invite their live audiences to join them side-by-side in the game, with a single click, while others continue to watch.
For those who don’t know, Amazon licensed the CryEngine last year, so Lumberyard can go in its own direction depending on what the developers are looking for, and at times it might even have an advantage over the CryEngine. This is seen in the low-latency networking code and an improved new asset pipeline and processor. The engine is currently in beta, but you can download it for free right now from its website.
