So, I've realized this after 3 days (Lemonade Tycoon days, which is like a minute of game time) of selling in the "Mall". The beach and the mall are capable of making the same amount of sales if the weather dictates it. If it's 80 - 100+ degrees out, I'm selling at the beach. If it's 50 and raining, it's the Mall or bust. I can keep the price the same, if it's 50 and raining, the mall people still pay $1.10 for a cup of lemonade, just like the beach people will if it's 100 and sunny. Obviously. You just have to learn the rules before you can assume that a program realistically simulates human tendencies. Especially one written for a cell phone.

Here, check out GameSpot's story on it... Lemonade Tycoon. I'm addicted, but soon, when my popularity in the mall gets to 100%, I consider that game over. I just want to be famous :)

From GameSpot:
Start small, and focus on the fundamentals. Lemonade Tycoon is a business simulation for our uncertain times. Beginning with just a tiny stand on a suburban street corner, you buy supplies, mix up a batch of lemonade, and hustle your drinks on the street. If your price is too high, the line is too long, or your recipe stinks, you'll be stuck with melted ice and spoiled lemons. With finely honed marketing skills, a canny grasp of what customers want, and a double-squeezing of luck, you can work your way into bigger stands, better equipment, and big-time venues, like the beach or a mall.

and...

The sim is deep and complex, with hours of gameplay for the dedicated sidewalk lemonade hustler.

one more:
As mobile games go, this sim is quite deep. Not only must you set the right price and buy appropriate supplies, but you've also got issues of weather, market awareness, demographics, and advertising. Stripped to the essentials, the dynamic and interconnected nature of business is represented here in a fun and clever manner.

They just make it seem harder than I do :) I have to admit, I am quite awesome at the game.. you might even call me a Tycoon.
