All in all, it's a great game, deserves a 5/5. There is a glitch. When upgrading stems, no matter how high your nutrient bar is, when you upgrade to Stem lvl 3, it all disappears.
Random Naked White Guys Glitch: Go to adventure, pick any one of them, wait until a guy appears, right click, hit play, make your way to adventure, choose any one of them, and see random naked white guys!
Okay, I did something I shouldn't have. I right clicked, then hit play. All of a sudden, my character, the board, and my enemy appear on the loading screen. I continue until I could adventure when suddenly, two random naked white guys appeared. Kids, do NOT try this at home!
Wait everyone! Before you rate 1/5, beat it. See the message. If you really hate it, you would vote 5/5. If you like it, you would rate 1/5. Just saying.
Ha, I decided to try nightmare. I started with one police station, one farm, two suburbs, 25% happiness, 25 food. However, there was a police station nearby, a mall, and an All-Mart. Surprisingly, there wasn't a lot of red zones until about the 10th day. After I ran out of food, it went downhill from there. I don't recommend trying nightmare!
