I'm currently playing this game. Looks amazing and the combat system is kick-ass. A welcome break from the left-right melee swinging in Skyrim. CDPR have distributed their bonus content appropriately. I'm still finding my way through completing the missions and learning their structure. Seems like you don't need to follow a defined path, but some side-quests have alternative approach. The choices really impact your progress. There are so many names being thrown around, sort of hard to catch up with at times. Alchemy is pretty easy. Skill tree is pretty well designed too.
Performance needs a bit of tweaking. Since the EE patch, the Cinematic DoF has been impacted, meaning, the cut-scenes experience severe frame drops. The best option is to disable it in the game settings. There are also texture streaming issues. I guess it's time to change my processor, as it's starting to bottleneck my card. But the game looks stunning, no two ways about it.
