GOG - Time Machine Sale
GOG is having a time machine sale going from 1983 to 2013 where you can buy games for big discounts. Here is how it works:
There's more than just buying games incredibly cheap to our DRM-Free Time Machine Sale! We're ready to pass its steering wheel (or rather the control console) to YOU. Each game in the sale is offered for a limited time only, and how long we stay in its year is up to you! Each time you see a new game on sale you can vote to either add or subtract 1 second from the timer. Each time you buy a game, you add 3 seconds to the time of it being on sale. We begin with 1983's Zork, bundled with the rest of the Zork Anthology of 6 games in total, for only $1.79. How long will it last on the front page? You'll be the judge. What comes next, as the game of 1984? Let's find out!
Currently it is in 1996.
