It's sad to see more and more topics with indications of the simulation being not just a little wierd but to be honest quite messed up. I still believe that this is a fantastic game and I will probably play it for a quite long time but it's a little surprising to me that wierd behaviors like this have made it to the final release version of the game. Hopefully we will see som changes in the next patches.
Yeah, there is a lot of bad stuff going on behind the pretty surface. I can forgive them for now though because they only had a team of 13 I believe, but with the huge success of the game I expect them to hire in some more people and deal with some of these quite fundamental problems. If not then I might less inclined to purchases the next game in the series.
Edit: I'd also like that add that I have plenty of parks and my commercial demand has always been high.
