After all this time I missed a good open world game with a nice dynamic world with story and I found it in Shadow of War.
This game does everything Shadow of Mordor does but better smoother and with more refined combat. Every battle and siege is different you have different options. You can dominate warchieft to become your spies in sieges or you can kill them all for a easy conquest. You can send Graugs and Trolls or you can prefer riding a drake for your siege. Same goes for defend side you can get better walls or spiked ones to prevent orcs from climbing. There so much option that I cant tell. I mainly focused on siege mechanic because half of the game takes place in those missions and this missions are how they promoted this game.
