My dream for GTA 6 is Carcer City based on Chicago then GTA 7 in Texas with Holster (Houston) and Darling (Dallas). Because then Rockstar can complete the Midwest and South. Then in GTA 8 you can bring San Andreas (West Coast), Carcer City (Midwest), Holster/Darling Texas (Southwest), Liberty State/Alderney (East Coast), and Vice City (Southeast) together to create a country. You cant do all 50 states, but the largest cities in each region can be brought together and San Andreas, Carcer City, Texas, Florida, Liberty City, and Alderney accomplishes that.
You cant have a country now because there is no Midwest or Southwest. You have to be careful creating Chicago because it's the third largest city in the US and largest inland city, so it has to be the MAIN CITY and should ONLY be included with 2 other cities if Rockstar is willing or able to make an absolutely huge ass version of GTA San Andreas' map capable of maintaining the scale and integrity of Chicago.
But it cant be like GTA SA where all three cities had equal scale. In any Midwest map, Chicago has to CLEARLY appear bigger and larger than everything around it. And it has to FEEL like it's the third most populated city after Liberty City and Los Santos. But if Rockstar isn't at that point yet, they'd do better just making GTA Chicago a one-city game instead of a super small half assed version of Chicago with the Midwest around it. But if XBOX One/PS4 allows them to be able to create maps so large that they can add other Midwest cities around Chicago WITHOUT significantly detracting from Chicago itself, I'd be cool with it. I just don't want a small condensed version of Chicago due to the fact of them adding too many extra cities around.
You cant half-ass with the third largest city. Same with, Texas should only be put in a game with other cities or states as long as Texas is the focus and is size isn't detracted. You have to do full justice to places like Chicago, Houston, Dallas etc. You need to really really be careful with Chicago, Houston, Dallas etc. Add sh*t to the map, but make sure those places are represented with full integrity and scale because those are the biggest places left to do in America after Liberty City and Los Santos/San Andreas.
All of it depends on what the XBOX One/PS4 allows though. If we can have multi-city maps where the scale of places like Chicago and Texas can still be done justice that'd be the best of both worlds. But every GTA since GTA SA seems to have these mythical "limitations" and excuses that pop up and never has the features you envisioned, so I dunno what to expect.
