The documents, which detail a subscriber's rights and obligations as well as how Valve handles sensitive user information, states that "customers may now only bring individual claims, not class action claims".
In an statement posted on the Steam website the Half-Life, Portal and Team Fortress studio said that while it believes class actions can be advantageous under some circumstances, for the most part they are only beneficial to the lawyers.
"In far too many cases however, class actions don't provide any real benefit to users and instead impose unnecessary expense and delay, and are often designed to benefit the class action lawyers who craft and litigate these claims.
"Class actions like these do not benefit us or our communities. We think this new dispute resolution process is faster and better for you and Valve while avoiding unnecessary costs, and that it will therefore benefit the community as a whole."
Valve also detailed its dispute resolution procedure when using arbitration or the small claims court.
"In the arbitration process, Valve will reimburse your costs of the arbitration for claims under a certain amount. Reimbursement by Valve is provided regardless of the arbitrator's decision, provided that the arbitrator does not determine the claim to be frivolous or the costs unreasonable."
Valve recently said is 'has no plans' to allow for digital pre-owned trading, however a new EU ruling suggests customers must have option to resell digital content may force its hand.
