Let me say something about non realistic fuel prices in this game.
First of all different parts of the world have different fuel prices. Some countries produce oil and some countries depend on the oil producing countries. Oil doesn't cost the same in other places because one produces it and puts the price tags on them while the others just buy it.
Some reasons why can oil cost so expensive:
And there is many more important reasons to it
Secondly for example in Riyadh which is in Saudi Arabia their petrol prices cost about 8 cents per liter and there is Rome in Italy which have petrol prices of $2.50 per liter. Thats why in real life Saudia is a forever expanding carrier while Alitalia is nearly going bust. Why? Oil prices are really high nowadays and Middle east are one of few places in the world that can get oil for couple of cents a liter.
So why is this game only based on one fuel price? It isn't realistic Sami!!! You have different airports which have different slot prices, parking and landing fees, staff etc but the oil has one price and one price only in the game and it rises and falls! How does that make any sense at all? Can you change so every place will have it's own fuel price per country in the game please?
But there is two disadvantages about this.
1. It will take a while for Sami to take all the data and then it will be incredibly hard for him to program it on the game.
2. It will give an unfair advantage to the airlines which are based in an oil producing country so they will grow quicker and get everybody bust.
PS I do know that Alitalia is getting knocked down by LCC carriers as well.
