I don't think congress meant to limit gaming so much. They just meant it for the movies and shows and all. There has probably been enough uprise for congress to see their mistake and take video games out of the situation. Also, if this DOES go through, many game producers have said that they will publicly announce (whether on the box of the game or otherwise) that they will allow such gameplay posting, as this (though not on purpose) advertises and helps game sales quite a bit.
I wouldn't worry
