We played some official deathmatch at a lan party once with some freinds. It took us about 10 minutes to go "this sucks, lets go back to CS".

So maybe they learned a lesson and let the mod community do all the work.
All a matter of opinion - I used to play HL1 DM against my roommate ages ago when HL was still new. We had our computers networked, and went one-on-one. When you don't have a large number of people, DM is pretty much the only way to go.

These days I mostly just play Enemy Territory, but even with that I find that servers with less than 25-30 people just aren't much fun.

I'd still like to see HL2-themed multiplayer levels with the HL2 weapons, not just CS:S. I'm sure it'll happen - but letting the modders do your job for you could backfire.
