Some interesting legal stuff with this engine, which their FAQ(1) goes over.<p>Basically, use it for whatever, free of charge, but not with any other cloud services that mimic amazon&#x27;s services(2).<p>Except cloud services for some things, which are fine:<p><pre><code>    Your game may read and write data to platform services and public 
    third-party game services for player save state, identity, social 
    graph, matchmaking, chat, notifications, achievements, leaderboards,
    advertising, player acquisition, in-game purchasing, analytics,
    and crash reporting. 
 </code></pre>
Is it a game changer?<p>Hard to say, but like they say, you can&#x27;t beat free.<p>If nothing else, a <i>lot</i> of people are going to download this and have a look at it and mess around with it.<p>Pretty exciting stuff. :)<p>[1] <a href="https:&#x2F;&#x2F;aws.amazon.com&#x2F;lumberyard&#x2F;faq&#x2F;#licensing" rel="nofollow">https:&#x2F;&#x2F;aws.amazon.com&#x2F;lumberyard&#x2F;faq&#x2F;#licensing</a><p>[2] <a href="http:&#x2F;&#x2F;docs.aws.amazon.com&#x2F;lumberyard&#x2F;latest&#x2F;userguide&#x2F;lumberyard-alternate-web-services.html" rel="nofollow">http:&#x2F;&#x2F;docs.aws.amazon.com&#x2F;lumberyard&#x2F;latest&#x2F;userguide&#x2F;lumbe...</a>
