Cookie Tycoon Pretty good game
I'm not too sure what some of the others are saying, but this game is pretty good and im making a lot of money. Im on day 29 and i have $107351.85. It just takes a while to get going, but once you do you can either roll in the money, or struggle a bit.
The one tip that i will give to people is watch what is being sold and increase the sale price if its selling, or decrease it if its not doing well. Its really not that hard...also buy low sell high. Thats what i did and look at what i got.
Right now the only complaint that i have is the pop-up takes too long to go away...also most of the customers either say "This could be better" or "wow that sucked." Sure i got a couple of people to say that it is pretty good...but i think that if everything is selling out, then people would have more "this is pretty good" and less "this sucked"
