I've already said in various threads that I loved the game on PC and it might be my favorite game this generation, even with certain issues which I realize.
Here would be my list of things they would need to improve or have in the game for me to consider it close to perfect, at least for this style of game, without being exaggerated:
1.Better AI and Police, without spawning from nowhere, better reactions etc
2.Better collision for everything: npcs, cars etc
3.Minimap to zoomout when driving fast
4.Car paints, at least have the skins that are already out in the world
5.More escorts to f**k
6.Space story mission maybe crystal palace or moon colony
7.Another corporate mission in a large building, like the Konpeki plaza one from prologue. Theres alot of missed potential here, for example the big Medcenter in Watson is there just for show, I could see a really cool mission in there, fighting trauma teams trying to hunt you or something.
8.Flying cars, mod at least ?
If this list is implemented, I would consider this game close to perfect. I think CDPR have it in them to do it.
