GOG.com started its "Battle of the Games" promotion today, in which players can vote on which games they'd rather purchase at a cheaper rate. The sale offers two sets of three games every morning at 7:00 a.m. ET, accumulating votes throughout the day to determine which set receives a 75 percent discount and which is 60 percent off the next day.

Currently, the digital retailer is pitting the trio of Red Faction and Red Faction 2 as well as Chaser against Unreal Gold, Unreal Tournament and Unreal 2: The Awakening. To get the sale started, GOG.com is also offering discounts on six games for the day: The first three games in the Heroes of Might and Magic series for $2.49 each, Blackguards Special Edition ($22.49) and the enhanced editions of The Witcher ($1.99) and The Witcher 2 ($3.99). The Battle of the Games sale ends April 21. [Image: CD Projekt Red]
