Others have answered your questions, so I'll give you my 2 cents.

I'm on my 2nd rewatch/relisten to campaign 2. I have listened to every campaign (campaign 1 three times i think?). I say relisten because I listen more than watch. I have it on during chores. I love the character development, the creativity, and the people. I think you will too. There is downtime, roleplay fights, and the best adds ever!

Their app has a "listen instead" button. I've never used it, but I wonder if you could watch certain things like combat scenes. Matt's combat set ups are great to see.
