Yesterday I was playing with some buddies in chat. Another buddy that isn't playing with us asked if we were doing the main quest line or side quests. I responded, "There aren't any main or side quests. You just kinda play". At that moment it finally clicked. BG3 is a game where you just enjoy yourself without a conception of what you're doing mattering or not. You put your own weight into your experiences.

This is pretty tough to do though since I see new ones crop up every day in my feed
