From May 24 to June 1, many noteworthy independent games will go on sale "to celebrate online stores that give us control over pricing." This initiative, dubbed Because We May, will include titles sold on PC, Mac, Linux, Steam, iOS, Android, and other platforms.
While prices aren't being disclosed yet, the selection is, again, excellent. Follow the links at the top of the site to see for yourself. It should also be noted that the list is still growing; if you happen to be a developer who wants to promote the project's message, you have until May 22 to sign up.
