The last remaining hours for GOG.com's 2015 DRM-Free Summer Sale are here. You have less than 16 hours left (at the time of this posting) to save up to 90% off of a ton of games. They brought every deal back for the final hours.

In addition, if you spend a few bucks here and there, they will give you Sim City 2000 Special Edition, S.T.A.L.K.E.R.: Clear Sky, and Xenonauts as bonuses.
