>>713829806 (OP)You should have played KF1 first before KF3 since it's basically the bare bones experimentation of the formual of the series.
It's more like a typical dungeon crawlers whereas 3 and 2 are more open world exploration and dungeon.
All of the game takes place in the dungeons including the npcs you talk to.
So if you can appreciate it for what it is you can still have fun and it's very short so you can go through it over the course of a night or two.
As for Ancient City, play it vanilla, it's going to be very slow in the beginning but you'll get used to it and adapt. It's also more like 2 than 3 though, there are no real towns like 3, the people you meet are spread out in all kinds of places.
