Microsoft has permanently cut the prices of seven Windows Phone Marketplace games to 79p / 99c to celebrate the launch of the Lumia 900.

In the process, the Redmond-based firm has established a new lowest possible price point for Windows Phone apps.

While Microsoft customers have been able to pick up the odd Deal of the Week title for £1.49 / $1.99, the starting price for standard games on Xbox Live used to be £1.99 / $2.99.

The full list of games permanently reduced to 79p / 99c is as follows:
