The early news is that S3 will allow you to play solo, along with NPC henchmen. Too early to tell if it will still require an active internet connection to do it.
thx,
excellent news; because, currently most of the developers have forgotten that a lot of people like to play SP game.
like Diablo 3, I guess! sad this is the reason why I don't want to play at this game. This is too intrusive.
