A common complaint about apps written for the Windows Runtime, also known as Metro by those outside Microsoft, is that they tend to show only a small amount of data per screen. The most information-dense Metro app I have found is a game, Wordament, which shows a fair amount of data in its results screen.
The word lists scroll, and so does the list of players. Which proves that you can create an information-dense screen in a Metro app; though it is all custom-drawn.
Games do not matter; and yet they do, for many reasons. One is that a great game makes you want to pick up a tablet, which means you will probably end up using it for other things as well. I admit, one reason I like the iPad is because it has Funbridge, endlessly entertaining for Bridge players, and not available on any other mobile device (though Funbridge has become expensive and I play it less these days).
If Microsoft is to make a success of Windows 8 then, it needs some excellent games, and Wordament is the best so far. It is not dissimilar to Boggle, a shake-and-find-the-words game which has come to iOS courtesy of EA after enduring popularity in the physical world. Wordament offers a grid of 16 letters and you have to form words by dragging your finger over adjacent letters – I presume this also works with the mouse but have not tried it.
What makes Wordament fun though, in contrast to Boggle, is that after each 2 minute game you get to know how you did versus everyone else who played that game.
It is the same as with Funbridge: the fact that you are competing with others, even in a fairly anonymous manner and with no prizes, transforms the game into something compelling.
Three or four exclusive games as good as this, and everyone will want a Windows 8 slate.
Currently Wordament is also available on Windows Phone 7.
