Why can't we be given a list of new features like this for the dashboard update?

Not that anyone will probably care....  We're all too busy with Halo....

Is there a list somewhere that shows which PC games are Live enabled (ie. with achievements)?

I understand the offline feature of achievements for games for windows, but it wil be really great and bring more effort, if the gamerscore offline can be added online to a silver or gold account on xbox live.

Plus, as i read before, is this a update because 250+ people ask for it in your latest blog:

If so, what can we see in the couple of months....

I was hoping that offline achievements would come for G4WL.

Right now, I believe the only two G4WL games are Halo 2 Vista and Shadowrun.

Gears of War PC is coming and will feature it, and Splinter Cell Conviction will also feature it.

When we will have the Windows Live app that was shown once , were you could be at your Vista Desktop browsing the internet and then see a invite from some one on your list and be able to see that invite and join them or just send them a message without being inside a damn game?

A very small step forward for Games for Windows.  I'm still waiting for guide accessibility from the desktop or sidebar.

Now all we need is some games to take advantage of this.

I definitely agree with XSAVAGE, accessibility to your Gamertag from your desktop was something we were really hoping for with Windows Live and it didn't come.  This will be crucial to making that platform truly flawless between platforms.
