To me Valve IS the PC industry. They have integrity, honesty, quality and commitment to the platform. AND they port to the consoles, the way it should be. Plus, their titles reek of quality over quantity and are scalable to any PC. Smart, smart, smart.
Plus, they release stuff "When its done" I have never played a Valve release which was obviously Beta quality, something that is almost standard with other pushier PC publishers who try to rush out games for targeted dates to make their stockholders happy. Programming doesn't work that way and gaming definitely doesn't!
