The makers of the point-and-click adventure game Machinarium came to a realization recently. Their DRM-free game was being pirated by about 90% of players. Such is life for a game that doesn't bother users with serials or authentication. A similar rate of piracy was found for the DRM-free World of Goo. However, the folks behind Machinarium are feeling generous, and are offering people the opportunity to participate in their new pirate amnesty sale .
Until August 12th, Machinarium (and its soundtrack) will cost only $5. It usually goes for $20. The game is available for PC, Mac, and Linux. In Machinarium you play as an unassuming robot traveling through a beautifully detailed world mechanical malcontents. We grabbed this game from Steam a while back, and can testify to its quality and challenging puzzle-based gameplay.
You don't need to prove you pirated the game to join in the fun. Anyone is free to buy the game during the sale. If you like point-and-click style casual games, $5 is a reasonable price to pay. You can check out a demo of the game, and buy it here .
