I think this is the best game for PPC out right now. If you have played one trading game you have played them all. The concept is the same but they add a better battle twist to the game. Instead of just being a trader you can decide to gain your income from hunting down pirates instead. Also instead of just accumulating a ton of money and having nothing to spend it on except a new ship this game gives you alot more avenues. You can build a fleet of ships, buy warehouses, or put your money in the bank and earn intrest. The grafics are really colorful so your eyes dont get board. Deffinately worth atleast downloading the demo.
