I can agree with this post a lot.
For me the most important infos for launchbox Android would be:
Cover , Video or Screenshots, Number of Players, Releasedate, Genre , Description of the Game
I think all this would fit in the theme of thewite posted above!
Also a very very important information would be that I can see how many games I own for the specific consoles or even all filter categories. When I swipe through my consoles in banner mode on android it would be super awesome if there would be a number of games I own for the systems 🙂
