It is so being overdone..
SOPA will be basically the same as the DMCA in most cases however a force shutdown.
It'll mean youtube is shutdown, megavideo, etc, but things like BC won't.
Private servers of existing games that actually are going somewhere might.
Expo won't be going. Nor will Enigmata. Under the DMCA we could've been sued already. Did we? No.
It won't be the end of the internet. It'll be the end of most communities on the internet, possibly making it return to its original state (the internet was created for research and learning purposes only).
--I will let it be known that I am an extreme anti-SOPA person. However you're all overexaggerating SOPA's power. I've followed it since early December.
