Do NOT purchase the steam version of this game you will not be able to play online without opening a support ticket with ubisoft to be issued a new CD key and this process takes a LONG TIME.
I cannot in good faith recommend this great game as a large amount of content will be completely unplayable without going through a lot of annoyance. I love this game and series and was really annoyed when i went to play through the series on pc to only deal with this right away.

wheres the dogs and how do i watch them

I had an epiphany about this game after hundreds of hours, it's ass.
