Valve's "Perpetual Testing Initiative" has already been yielding results, and they provide evidence for the hypothesis that people still like playing Portal 2
. Since the DLC's release on May 8
, the company reports that over 35,000 user-created maps have been uploaded, which have been downloaded over 1.3 million times.
To celebrate this successful experiment, Valve has discounted
several items on Steam, including, of course, Portal 2
, which costs just $6.79 right now! Fellow Steam Workshop title Skyrim
is on sale for $40.19, and several Workshop items within Team Fortress 2
can be found for 50 percent off.
