Correct me if I&amp;#x27;m wrong, most games don&amp;#x27;t use UI components (most of the time it&amp;#x27;s a full-screen game) the way regular apps do so I&amp;#x27;m wondering if RoboVM is a good fit for Rich-UI mobile apps?</text><parent_chain><item><author>badlogic</author><text>We&amp;#x27;ve been using a similar approach for libGDX [1] with great success for the past 3 years.
