Got a PS4 Pro and have questions/comments

So I finally switched over to PS4 recently and have some questions and comments:

1. Best games for the Pro? Cheap games that can keep me satisfied until fall when all the AAA titles release

2. Holy shit this thing is powerful. Got BF1 on it and was amazed by how beautiful and different it looked compared to it on my Xbox One. I wanted to get the One X but my opinion of Microsoft has dwindled over the past year.

3. Thank god I can switch the hard drive out. Games load so much faster and it feels like my PC in terms of power, which is what I wanted since I'm trying to slim down my gaming collection as I grow older.

4. Best multiplayer game in your opinion?

Thanks
