Why is this game so complicated? I have tried 7 times to play this game, and every time I have given up. The more I try to play, the more confusing it gets. Why isn't there a step by step tutorial that can explain things clearly and simply? I don't think I will bother to play this again, and I don't think I will recommend this game to anyone.

The rest is just knowing how to get stuff at a decent price, and sell it at an even more decent price. If some product is not worth the cost to get it, skip it and to the next one.
The learning curve is steep but once you get the hang of it it is a TON of fun. There are a bunch of guides in the FAQ forum, read them, they offer a lot of info on how to get started.
