I propose all of New England. Maybe then we can get that highspeed rail line that NYC and Boston were trying to build back in the 2000s. Between that, the two international airports of both cities, the multiple major ports across all of coastal New England, the high rates of college educated workers (a whopping 80% of the workforce in Boston, highest percentage in the country), and the wealth of residents across the area, there's a lot of benefits there.

Denmark (or any other EU country, really), is there any way that I can make this deal more appealing? How about if I told you that Rockstar has a studio north of Boston and that by taking New England you could get GTA 6 faster?
