Was looking at a saved page from your site for Fallout 3 in a playable setup for windows 7 and decided to see your updated Fallout New Vegas as well. nether of the steam versions are playable hoping yours where. but nothing I tried would get me to a store page for anything. Also in the systems requirements for Fallout 3 did not specifically state that that is was compatible with multi core cpu's say 4+.

The store pages are here, are you unable to view them?

Do you get some kind of error message when you try to view those pages? What does it say?

If so, which browser are you using, could you update it or try another one?

EDIT: Regarding system requirements, recommended specs for Fallout 3 call for a Core 2 Duo, which is a dual-core. So presumably the game must support multi-core CPUs.

I see the page but there are text overlaying each other. I can get the store drop downs with graphics but none on the main page. I am using a recently updated version of windows explorer. I did find a way to get the fallouts in the cart and clicked the PayPal tab and it would not bring up the page to authorize it. it wont let me buy the games.
Thanks Rich

If by "windows explorer" you mean IE, ever since the October redesign they made the site no longer work in it and specifically said that won't change... though recently I'm seeing some game pages, but definitely not all, start to work, oddly enough. And there are still some ways to get things to work, off the parts of the site that are still in the old format, may need different ones for different functions.
If, on the other hand, you mean Edge, it likely falls under the "less popular browsers" that they said they don't and likely won't test for anymore. Should still probably work though, and really should on the new Chrome-based Edge MS is developing, since Chrome is what GOG codes for, with the very latest FF the only other thing they actually bother to test in and actively fix issues with once they notice.
(If you actually meant Windows Explorer though, um, that's not a browser.)
