Why isn't there any "Other Games" section for the Left 4 Dead Series?

I feel like we could have a whole new support thread and everything for people's technical needs and grouping half way competent people together to play advanced, expert, versus, etc.

I used to love the first one, never ended up getting the second one I felt like it was too much of the same shiz.

I never actually played the first, I would like to though.

I'm hoping the third is a lot different, seems like they didn't change a whole lot from L4D1 to L4D2. Hopefully L4D3 is a complete redo on graphics, etc.

I saw a L4D3 trailer on Youtube, but I'm pretty sure it's a hoax, looks like L4D1 graphics with custom character models, special models lol
