For six years now, we've been building a library of great games of many genres, ages, and origins. One by one they were introduced to our catalog, publisher by publisher, developer by developer, series by series. We've started small, with just a couple dozen of games and a small crew of passionate gamers. Then we grew. Each year was exciting and brought excellent additions to our offer. This week, we'd like to go back to GOG.com history, taking you on a little trip down the memory lane. Each day we'll be taking some of the games we've released in a given year of GOG's existence, and offering them to you up to 80% off.The sixth year of GOG.com, the year we've just now completed (starting September 2013) we will always remember for the sheer amount of awesome things we managed to pull off. We've introduced an unmatched Money Back Guarantee. We gave away the originaltrilogy, as well as the classicfor free, to the gamers around the world. We've promised and delivered Linux support. We've launched our DRM-free movies. We've announced GOG Galaxy, a DRM-free Online Gaming Platform. All that, while maintaining our main focus: expanding our catalog with great classic and indie titles. One of them was Banished , a phenomenally well-received game made by a single person. Here's what our community member, Mordam, had to say about it:The year 2013/2014 brought many more exciting titles, classic and new, including S.T.A.L.K.E.R.: Shadow of Chernobyl SimCity 4 Deluxe Edition , or Risen .
