so Beth/Obsidian legally cannot release a regular patch if they wanted to. well here's to hoping future beth games wont be Steam exclusives.
I have no clue about the legalities but I can say that I am happy they have found a new way to deliver patches and content other than the overloaded servers/mirror sites and such of yesteryear. It was sometimes a nightmare trying to get it downloaded when they came out.
It's just how they deliver the patches and extra content now. Fallout:3 was GFWL and while that was better than when they did it themselves, there were still problems. Steam has a proven record of getting the content out there much more quickly. :shrug:
Xbox will be getting them through Xbox live and so on and so forth.
