GOG's DRM-free Time Machine Sale puts you in charge of bargain's lifetime
GOG is throwing a sale on 30 games from the past 30 years, but it's put an interesting twist on the promotion. Every time you buy a featured game, you can choose to add or subtract from the length of time the discount will be available to other punters. Price reductions range all the way up to 90% off, meaning some titles cost even less than $1. Several games have already passed through GOG's Time Machine sale, so hit the link, pin the tab, and keep an eye on it.
