Well it looks as though my saves have been sabotaged in some strange way possibly. I hope there's a way to get them back. I had 2 sandbox games that I was playing and one of them was to see how much stuff I could build before the game started to slow down. Quite a lot from what I remember!
I swear housing seems to work differently on different maps. That or the concept alludes my brain in some way. I was playing the mission where you need to scan the 3 buildings the other night (on the hardest setting), I had minimal issues with housing penalties and didn't feel like I built any more housing options then I normally do. But most missions I feel like my approval rating is suffering a lot more because I haven't made enough housing for people to live in. I like the system they have for it, I just don't fully understand how the penalty gets calculated.
I haven't checked out that video since before I bought the game. Did they update it? I will try to look at it later. It's hard to watch videos at work until lunch time.
