5 huge cities.
huge playground in between with lots of things to do.
lots and lots and lots and lots and lots of villages, including bigger villages/micro cities
All eco-systems present. dessert, mountains, snowcountry, tropics, oceans with islands, huge lakes, rivercountry etc. all types of terrain u can think of.
flying from one side to the other in commercial jet at highest speed should take at least 10 minutes prefferably more.
train system that connects everything (high speed trains, otherwise the will generally not be used often)
serious wilderness this time. Huge!! meaning no roads nearby and plenty interresting stuff to do. mountain slopes with nothing to do like in GTA V is absolutely not acceptable. u could at least make a village on the mountain or something so there is something to go to..
but Rockstar will never make that.
because Rockstar is now Cockstar.
