First, in this game knowledge is power. Second, Dark Souls isn't some cheap-shot super hero game where you can mindlessly spam attacks and win. Keep that in mind and soon you'll find that this game is quite entertaining. If not, try to get a refund and move on, this game isn't for you.
Remember that all the games are digital distributed. It means that it doesn't cost THQ anything (except for the share ratio with the partner in the deal). And thus, all the money they get turn into profit, not revenue. I think we need more of this during the holiday season.
