I did some more Orc killing. I'm not enjoying this game quite as much as its predecessor, and I can't see any reason why, it is as good as or better than Shadow of Mordor in every way. I guess the gameplay doesn't have the staying power I had hoped for.
I reduced the difficulty to Normal and completed Act I. I can't seem stream to YouTube in high quality 720p from my PS4 today, so to record gameplay I use the built-in recording, which maxes out at 1 hour. I then set an alarm for 50 minutes and wrap up when it rings, and then save the video and upload it. Extremely annoying.
I just realized that the problem of not being able to stream this game in high quality is not due to network problems, but due to a limitation imposed by this specific game. I'm going to try streaming in the highest quality it allows, and see what it looks like, which should be less frustrating than recording 1 hour videos with an alarm clock. :/
