I REALLY like the idea of using the flyer artwork to sort through your game library

It's similar to the same way so many of the movie media players use the dvd/blu-ray artwork etc, here's an example of mine for instance:

An equivalent for games which also shows a video snap of the game being played would be awesome!
The top LEFT half of the screen needs some work tho to look as polished as the lower half of the screen. I'd leave the box to display the video snap where it is but on the left I'd have a large stylised text box that displayed a little info about the game, story, release date, manufacturer etc.
Good luck with it Oomek
