Last week, Valve expanded its Steam Workshop to allow mod makers to sell their works directly to other players, using The Elder Scrolls: Skyrim to introduce the concept. Lots of people got upset, for a number of reasons. Some were upset because they thought mods should be free. Some were upset because they thought mod makers deserved more than the 25 percent cut of revenues Valve and Bethesda were giving them. Some mod makers were upset because their free work was being used in mods for sale. Gabe Newell was upset because Valve was being accused of short-sighted greed instead of longer-term greed.
