Wrong
You know why Valve took 6 years to develop Half-Life 2? Because they put real effort into it. Half-Life 2 is their only 'deep' game? Fuck, even Team Fortress 2, a multiplayer-only game which started off with barely any story now has a deep and enriching back-story. Portal 2's story was utterly fantastic, and I'm learning new things about it even now I've completed it. Even Left 4 Dead, another game which started off with no real story now has a compelling serious narrative behind it all.
To say that Valve's games are shallow is to say that you've obviously never played through them properly, or haven't actually tried to enjoy them. I'd go on to insult you, but that would be immature of me and would probably put me on probation
