The underlying ethos of Shadow of War seems to be more. More types of orcs. Your playgrounds are bigger. The number of things you can do is overwhelming. There are also plenty of combat options. And with Talion's ability to swiftly climb everything, the game often feels like it is brimming with possibility.
Let's keep this simple: Total War: Warhammer was a very good strategy game. Total War: Warhammer 2 is better. The game continues Creative Assembly's tradition of building on the release of a new Total War with a sort of semi-sequel. Only this time TWW2 almost does feel like an all-new game.
