We’ve already heard about the new downloadable content support for Steam, and the matchmaking is the same we’ve seen in the PC version of Left 4 Dead, now available to publishers and developers worldwide. The most interesting new feature is Steamworks new anti-piracy technology, Customer Executable Generation, or CEG. CEG basically creates a unique copy of a game for each customer, which can then be played on any compatible PC without install limits or root kits. You buy a copy, and that is your copy, completely unique to you. A simple and elegant solution to PC game piracy that manages to benefit both publishers and the consumer at the same time.
