I doubt there will be a sequel. GTA6 comes out next year which will rule for next 10 years in open world design. Thier chance was this only. Don't think they can match GT6 level anyways.
I think CDPR should make AAA Single player games only. Every 5 year a new game. Story, cutscenes with gripping narative with decent gameplay is there USP. By god some side stories in Witcher 3 were better than most games.
I think you’re in early parts of the game, give it time, the city is quite good, it grows on you….btw, it also has open highways and deserts.
When I played I was blown away by the verticality and the density , especially the place near the delamain hq, and those mega buildings and Asian towns.
Only gripe is that the world is not interactive like rdr/gta games, it just sits there like a wallpaper. Hope they improve on that in the sequel.
