The only reason I signed up without hesitation was because it had ATI (my card) and HL2 on it. Now, someone explain what the **** that just did for us?
Here's my theory: You gave them your email (identification), graphics card (specs), and name (uhh... name.). Why, why, why, do they need these pieces of information? Well... tie that in with "be one of the first to experience", and I believe we may have a limited edition link to a demo file in our inbox in the very near future. Here's to hoping.
