So.. I downloaded the demo for this game, got totally hooked. Thought "Well it's normally 30 bucks and now it's only 8, hell ya I'm going to buy it"
Go to the Steam store and there's no add to cart feature. Head over to the Steam forums and there's loads of people with the same issue.
People are talking about how they didn't have enough CD keys and that's probably the reason why there's no cart feature.
If that really is the case I think that's completely stupid. The whole point of going to purchase a digital copy is the convenience of it. You don't have to waste time or materials for it.
This is why people steal music, videos and games. Even when you go to get a digital copy of something it doesn't work or is unavailable. That and you can't compete with free.
I highly recommend this game to anyone that likes medieval themed game's.
