I enjoyed Half Life 2 and Portal - both great games - but then I started to play Half Life 2 episode 1, and a big pink and black chequered cloud obscured my view.
This is because EA ported the Orange Box pack instead of Valve, and coded the port so badly that technical issues such as this blighted the PS3 port of this popular PC game pack.
This pack should not have been sold , there should have been a product recall.
As it is, EA say it is up to Valve to produce a patch, and Valve direct people to EA customer service to get a patch; and no patch was ever produced to mitigate the technical issues which arose because of this bad port.
My advice is get this title on PC, not PS3.
