The problem with asking about the game's length is the definition thereof and how much it matters. Users have already mentioned that CP2077's main quest is apparently smaller, but the game overall should be more replayable. Does that make the game shorter or longer? So, how much that the main quest length matter? I am rather more curious about the side-quests and how much you can just "screw around" in the world for fun.
I do like the Witcher 3, but the open world aspect was generic and boring. Like almost any other open world game, you had "points of interest"; well, after the gazillioned Nekker's nest, I get the point. Nothing about it was "organic" or weaved into the world. However, with CP2077, I do hope everything is better connected and more interesting and unique. Incidentally, I do hope for a lot more verticallity because this was also sorely lacking in the Witcher 3.
