Maybe not, but maybe they should. Maybe the way people think is simply inaccurate and out of date. Why, people thought urine was a health elixir...even in this century. Times change, and people eventually upgrade their way of thinking. Such as accepting the idea, that 30 days trial, measured in per hours used, is actually brilliant and will increase sales. What is more effective? A casual gamer, who downloads Game Maker one day, with vague and lazy ideas of games. Gives it one use, then forgets about it. Then, many months later, he is inspired to have a brilliant game idea. But sadly, his free 30 day trial has expired. It has a feeling of never getting a chance. Like he was jipped. He will probably uninstall out of frustration and dejection. But instead...imagine this. Imagine he has a 30 day trial based on hours used. He builds his game for many, many hours, creating a game like he always imagined. And when his game is 90% done, suddenly he runs out of hours. He has invested so much time into this he can't quit now. He will immediately run to the marketplace and buy it, no questions asked. Tell me...is this not a better strategy?
