Could you include the Android / iOS projects for comparison

Would be a great extension to the repo and the porting articles to show the original iOS / Android projects (if available) to see a before and after porting to Windows / Windows Phone.

This will help highlight to existing users the steps through code that need to be taken in consideration and supplement the steps highlighted in the Porting guides.

thanks fro the suggestion. I get where you are coming from, the Platformer game sample actually runs pretty well across all platforms so the stuff we've added is really "light up" features. It's very difficult to provide a "real world" example of all the problems and issues outside of the code samples simply because these issues cause the game not to compile or work properly! You can get the original project from the unity store via the settings charm in the windows 8.1 version of the game, or just search in the asset store.

Well like you say, it's adding those platform specific features for other platforms.
As for the breaking stuff it's about having precompiler sections showing the differences between each platform or text to show best practice across platforms.
Show how would I architect a iOS game so it will work more effectively on other platforms, same for Android, WP / Win 8.
Things to avoid in code.
