Steam does all the advertising on its system.
The makers ED have stated for some time when it changed in beta to online only SP. Due to how they made the game work.
See the thing is its online SP.
How they worked the universe is they made it to require peoples interaction. Meaning the markets etc move based on the other players. They realised that this wouldnt work in actual off line mode. I can understand that people are ticked because they wana be their lovely naughty selfs. But I have to say the game is really not hard at all and many others will say the same. But like I said I understand why people wont like it.
Suit yourself you are still missing out.
