Personally, I think Valve are both increadible and lazy developers. Half-life, portal and L4D are all AMAZING games both in my opinion and the general public. But the fact that they don't want to invest the time in learning the PS3 architecture, the fact that newell in the past didn't want to work on consoles before saying they were "too hard to develope for" and that their graphics engine haven't improved since HL2 just gives me the impression that they are increadible but lazy. They make games that are fun, inventive, and atmospheric but generally lack a little something imo. L4D I also thought didn't give me nearly enough content for my buck and I was sorely disapointed in that.
