Our startup develops a HTML5 game editor called Construct 2, which is a Windows desktop app (Win32). We&#x27;ve been running about five years successfully with that. I&#x27;d say depending on the market it can still be relevant, but I don&#x27;t know for how much longer - Windows in particular seems to be trying to drag developers away from Win32 and the new Windows Store UWP apps. Note that Windows Phone and &quot;Windows RT&quot; can only run Windows Store UWP apps, with poor support for Win32. MS continue to push UWP hard and I&#x27;d expect to see more MS hardware in future with no Win32 support, which is a little worrying, but doesn&#x27;t seem to be happening fast enough to cause any kind of panic.<p>I&#x27;d add while mobile seems to be the trendy place to start a startup, most productivity apps are still easier and faster to use with a keyboard and mouse. So desktop-first can make sense sometimes.
