making games are hard Im aware about that but they didnt made a "new" game unfortunately. Adding 2-3 features with bugfixes doesnt make a new game.. <.<

Eh, I'm not really the sort to label developers as "lazy".
Making games is hard, and TpF2 is made by a tiny team of about 10 people.

agreed. Devs are too lazy to make those stuff so modders will do the rest it seems. Funny thing is they are probably gonna release a dlc for tf2

I did boost passenger capacity a little, but the real issue is more that the game is lacking some larger aircraft. Since people are actually interested in taking aircraft this time around, it would benefit from having the 767/A330 and 787/A350 capacities to help cope without the runways getting overwhelmed..

Im gonna create a realistic passenger vehicle sizes mod. Will add you to credits too ^^. Airplanes with VERY SMALL passenger spaces was making me mad too...

It will if its done right. I've edited almost all the passenger aircraft in the game to have an additional compartment that can only carry mail and unsorted mail from another mod, since that's a common enough arrangement with airlines.
And other vehicle balance tweaks in general.
