Back in the 2000's, RealNetworks had a desktop application where you were able to download games from. (as sort of like a predecessor to Steam) It shut down back in 2013. Am I the only one that remembers this?
Because they've been so difficult to find these days, I started a project based around preserving its RGS files through the shared efforts of me and others. (the type of file extension used for its installers). We currently have 344 of them.
