"In his review of the Xbox 360 version, Crispin Boyer stated that "The Orange Box is the greatest quantity of quality gaming ever." This is still (mostly) true of the PS3 version, but some technical hitches keep it from reaching the same level of greatness as its 360 and PC iterations."
They go on to say:
"Despite several technical deficiencies in this port, The Orange Box is still one of the most rewarding gaming experiences of 2007. We do, however, recommend you steer clear of the PS3 version unless you don't own an Xbox 360 or a PC with a moderate graphics card."
