Redmond's contributed two fresh game titles to the Windows Phone 7 Marketplace in the last couple weeks, both at $2.99, that should keep you entertained for a few minutes at the very least: Rise of Glory and Revolution. The former is a World War I flight simulator that features both campaigns and single-mission modes; the latter is a little more abstract, featuring "machines" that need to be solved by placing cogs in the correct locations... so yeah, they've definitely covered the gamut here. It's certainly good to see that Microsoft's still putting its money where its mouth is with first-party titles for the platform -- now it's just time for a little Halo, if you ask us.
