title: XNA alternative
body: <p>I recently switched to VS2012, managed to get XNA4 project working, but then I was wondering if VS2012 no longer supports (so really) and XNA seems to be such abandoned stuff, if there is an alternative to use, that is like:</p>
  
  <ul>
  <li>vs2012 compatible, and net4.5, c#</li>
  <li>not too high level (or well written and optimized)</li>
  <li>easy to learn after XNA</li>
  <li>free</li>
  </ul>
  
  <p>Priorities are from above.</p>
