Free the in app purchases

I can agree some of these people here... I loved airtycoon but to have to buy some of the ships and more port well... I got to the high level ships( 4 star) quickly through the use of loans. It was then that I noticed that you have to buy the better ships(5 and 6 star). For the 2 dollars I payed to get the app, another 2 dollars for 50 extra ports and 8 luxury ships? Does the make sence? I am not going to buy these in app purchases because I do not think it is worth it.
