It's clear that a lot of people wait for weekend PC game download sales before making their move to purchase a game. Such is the case with Risen's weekend sales event on Steam. The 2009 released fantasy RPG from developer Piranha Bytes and publisher Deep Silver can currently be bought for just $14.99 until 1 pm Eastern time on Monday.

However it looks like the sale was too successful as many people who paid for the game on Steam cannot get the required activation key needed to play the single player only game. The reason? There are currently not enough keys to go around. A post on the Deep Silver message board admits that they did not expect the amount of orders from the sale to be so large. The rest of the activation keys are expected to be made available to Risen purchasers sometime on Monday.
