Yeah, the first time is really hard to understand. Same thing happened to me. No one really bothered explaining anything to me. But then other times I've played it's been a ton of fun. Like, one of my current characters is a sassy dragonborn ranger who really likes treasure. Another one of my characters is a really deadpan psychic who is the wife of a god of nightmares. My third one is a grumpy lionfolk warlord who's seen too much of war. I could go on for days about my characters and their adventures.
Sometimes I do that. There are some people that I watch pretty much everything that they put out. Like Markiplier and Captain Bugman.
