Which windows app is worth its price?

Question

Windows phone has currently gone quite popular but still has a high pricetag on all the apps and it is hard to determine which apps are worth buying. So which app for windows do you think is worth its price tag?

Answer 1

From my point of view, it`s a game: Halo, Spartan Assault ($6.99)

I use to play it during my subway ride to job. Naturally, it doesn`t bring you the real experience as playing it on your console, but it`s a good tool to spend your time
