I present to you: The Second Street Update Concept
Given how many Update Concepts we have recently see here, I thought I'd throw my own hat into the ring. In my Opinion what the game needs way more than another location is a map expansion of its already existing Areas. Above you can see, drawn using my wonderful paint skills, my idea for this which I like to call the "second street" expansion. The Docks, The Suburbs and Northtown all feel very barren to me, whereas Westville and Downtown/Uptown are way more lively, even though they are equally not very big.
I think that by adding these Areas we could not only expand the map without adding a whole new area, but also improve the gameplay flow where it is most lacking.
The Early Game as it currently stands is basically nonexistent for experienced players, as a Proper Day 1 and 2 can get you almost all the way to Meth, which skips the dingy Northtown almost entirely in favor of directly unlocking Westville as soon as possible, which is why I think Northtown deserves an Expansion, which could then be used to slow the game down.
The Docks are currently almost nonexistent as an Area, as you have nearly 0 Reason to actually go there outside of deals and End Game Builds if you play until unlocking the Docks Warehouse, which is why I think that both the Docks and the following Area, Suburbia, deserve and need Expansions.
Suburbia would benefit massively from an expansion, as right now it doesn't even really feel like Suburbia, due to a severe lack of everything that makes Suburbia so bland and boring, being only really an Area you go to once to unlock all the customers to skip directly to Uptown, and then never again, since there are 2 Deal Locations in Suburbia and 1 Dead Drop spot. Expanding Suburbia would allow the Benzies to set up more solid defences right before the finish line in their Home Turf, whilst also ensuring that the most profitable Customers in Uptown are locked behind an actual achievement. Wrangling Suburbia from the hands of the Benzies right under their Noses.
I also think Downtown deserves an expansion, purely because I think a downtown should be bigger, but that would require too much effort to do in paint, so please just hallucinate it.
