Blackwater was too empty and too small. When I realised BW was where he travelled from in the first place I was disappointed - I assumed he was from some big bustling city, not a couple of empty roads and half built houses. Where do all the people live? In one hotel?
If there is a city, and I presume it would be BlackWater, it needs more going on. It needs atmosphere, grunge, people standing in doorways, houses, busy sidestreets, people selling stuff. BW in rdr1 was cold, boring, empty and devoid of any sort of atmosphere.
