Hi! First time commenter, but this was such a fun exercise that I had to share. It was a tiny bit confusing to start, as it seems like a lot, but you get the hang of things very quickly. I agree with kumada1 - this is great for those who like writing stories/novels, as it gives you complex characters in a flash, which gives you a great starting point for writing.
Overall, kudos to the creator - a fun and unique exercise that takes no time at all and yields some pretty great results!
