My friend and I are looking for Dungeon Siege 2 online, but are too expensive. But I stumble upon a forum online where someone said he/she called 2K Game and ask if Dungeon Siege 2 Broken World comes with DS2 and the 2K Game guy said yes. So I was wondering if this is true, if I buy Dungeon Siege 2 Broken World, I can play both DS2 and DS2 BW?
