Wow this quite the over reaction and people wonder why gamers are seen as entitled. I don't know why they didn't put it in the game but guess it might be more complicated to implement that you think it is and if only a very small minority will play the game that way in single player it might not be worth the dev time to invest in making it work. Either way you wont get an answer by throw a fit like this and accusing them and saying FU to single players or slap in the face or whatever over used phrase people throw around when devs don't cater everything to them. Also so what if they decide they just don't want people to play this way it's still their game and their vision not every game has to have everything for everyone.
