Your example doesn't work because here, you paid for the car, then you paid for extra. Here, we paid the game when we buy it, and we keep buying it every months
keep buying it every months
I have FF14 - i pay for it - i sub 10$ every month = unfair, "optional" stuff should be free
I have a Car - i pay for it - i pay the gas every WEEK which cost DOUBLE (even TRIPLE) the amount of FF14 sub = its fair

its not just FF14, its not just dealing with car, thats how every market works. clothes shop, electronic shop, everything, you buy a new iphone and the staff will ask you for "optional" stuff like the stand, casing, extra charger cable, etc. and you tell me i ask them to "give me all of those for free because i buy your iphone" ?
