The non-profit PC Gaming Alliance has been around for over two years now and today the group that's dedicated to both promoting and improving the PC game industry announced they have taken in three new companies as members. Two of the new member companies are hardware oriented. Corsair is best known for their PC memory products while Logitech is one of the biggest PC gaming peripheral makers.

The other new member is Arxan Technologies, a software company that offers, among other products, ways for publishers to protect their software from piracy (i.e. DRM). In addition, Razer who has been a member of the PC Gaming Alliance for some time, is now a new member of the group's Board of Directors.
