Yesterday i was doing the flying races in GTA San Andreas and when i did the Heli Heli missions i just noticed how difficult it was compared to the others, and I thought a bit about it and then during the mission i noticed that Los Santos looks more complex compared to the other cities, it could just be me though, but if that's true then it might be due to Los Santos being the first city you are dropped in, and they have limited hardware so they want to get a great first impression of the map by focusing on Los Santos, like Los Santos has some tight spots, lots of hills and downhills, drains and tunnels and highways, sure San Fierro (especially the hills) and Las Venturas might have that but i don't remember that many of them, so i think Los Santos looks more complex which is a detail i doubt anyone really thought about, once again this could just be me but i wanted to point it out because yeah, why not, let me know what you think of my thoughts
