Buddhism. Was raised Christian and my parents forced me to continue going to church even when things started to not make sense in early high school. Went from "You must go to church with us," to "You must go to church SOMEWHERE."
In college, I considered Islam, Taoism, and Buddhism but nothing stuck so I stayed with what was familiar. Finally came back to Buddhism a couple years ago and was like "Yep. This is it." To me, Christianity is a constant moving target that will never be reached in terms of what you're supposed to do and not to and it will generally always be your fault when bad things happen because reasons. It's something you have to carry with you your whole life.
When I first really started learning about Buddhism and learned that it's like a raft that you use to get yourself across the river and you out it down when you don't need it anymore, I was like YES PLEASE SOMETHING ATTAINABLE, EMPOWERING, AND MAKES SENSE.
This one was a surprise for me too, got LOTS of gameplay out of the demo and looking forward to the full game!
