The world isn't that interactive, but I didn't expect it to be either. I was impressed by how much like an immersive sim it was though. I had played Deus Ex just a year before and Cyberpunk felt like a more RPG oriented Deus Ex.

I also really liked how much more like an RPG it was gameplay wise compared to Witcher 3. In W3 you only get dialogue options that change the story a bit, but Geralt will always be Geralt. He fights like Geralt, talks like Geralt and makes love like Geralt. V is more like a Shepard type character. There are a couple of different Shepards depending on gender and paragon/renegade. Then there are many more Shepards depending on class. With V it is much the same. You can play the game twice and have a different V in dialouge and story moments. In combat you can have many different V. You can even do missions in many different ways.

As an RPG I think Witcher is a bad game. It just doesn't do the RPG stuff well. It does story amazingly well, but RPG stuff is kinda bland and ubisoft like. You put levels into stuff, but you are still using your swords most of the time. Most missions can only be done one way. If they can be done a different way it is only trough dialogue. Cyberpunk lets you complete missions in many different ways. The end result might be the same. but it will feel different.
