Tell me about it. I started that game a while back and at first I was having fun in the starting area right outside my house but soon I exhausted most of what there was to do there. I decided to try visiting one of the more populated areas but it seemed like the game was designed so that getting there without use of a vehicle would take a ridiculously long time. The game developers wanted me to pay cash for their "public transport" system which was crowded and not all that reliable so soon I was hooked and had spent a even more of my money on a vehicle of my own. As it turns out even that requires "fuel" and "maintenance".
Typical freemium model. They reel you in with F2P and as soon as you're hooked onto food and oxygen and all that you find out it takes in app purchases to have any fun.
