You can play either and they are both fantastic. wotr then kingmaker might be a better order though since imo the difficulty curve is better done in wotr so it might be the easier of the two to learn the system with
I really enjoyed road 96 and the prequel. It took me a bit to warm up to the prequel’s skating thing but I ended up really enjoying my time with it. I am looking forward to seeing what they do next in that setting.
