Context: O3DE is an open source (Apache 2) AAA game engine based on an updated Amazon Lumberyard<p>I've had the opportunity to work with O3DE over the past few months at work and I'm very excited to see where it goes.<p>There are two pieces of context if you don't work in the games industry (when I came in from an 'open source' background these surprised me):<p>1. the best game engine tech in the industry is proprietary (the biggest players are Unreal and Unity, lots of studios have purpose-built ones), there's relatively little open source [0]<p>2. in a games studio, the workflow of your company orients around the workflows of the game engine [1]<p>These two things combine in quite unfortunate ways, to the point where EA mandated the use of its own in-house engine...with mixed results so far [2][3]. Smaller players have three options: a) suck it up, b) use an open source alternative (i.e. Godot), c) get caught in the tarpit of "build your own engine"<p>O3DE has an opportunity to shake things up - particularly because of how modular it aims to be. At Hadean, our interest is in the networking layer (to drop in as netcode for Aether, our distributed simulation engine) as well as the 'core' simulation layer (to integrate with Aether in order to scale O3DE games/simulations across multiple machines). While doing all this, we will probably 'get involved' and contribute, so that our usage doesn't drift too far from mainline.<p>Anyway, this is all very early days - it's just a developer preview, and the flows are a bit rough. It'll be a while before we see if this changes things (I'm hopeful!), but major credit to the people at Amazon who have made it happen so far!<p>p.s. a checkout with deps, plus fresh compile of O3DE, plus a new project that you've opened once (to process assets) will set you back 100-150GB at my last check - not unexpected if you're used to compiling Unreal!<p>[0] <a href="https://twitter.com/ID_AA_Carmack/status/1406427706980454406" rel="nofollow">https://twitter.com/ID_AA_Carmack/status/1406427706980454406</a><p>[1] <a href="https://isetta.io/interviews/AmandineCoget-interview/#the-modes-and-pipeline-of-an-engine" rel="nofollow">https://isetta.io/interviews/AmandineCoget-interview/#the-mo...</a><p>[2] <a href="https://twitter.com/kingcurrythundr/status/1083788720459972609" rel="nofollow">https://twitter.com/kingcurrythundr/status/10837887204599726...</a><p>[3] <a href="https://screenrant.com/anthem-frostbite-engine-development/" rel="nofollow">https://screenrant.com/anthem-frostbite-engine-development/</a>
