You know it's funny since you've mentioned DnD, there was this one time I've played with a group while coming over to their house. But after one or two of us had to leave the country, we decided to use Roll20 to play DnD ourselves. My character was a Tiefling mage and man I had a backstory for the guy.
Sadly, we couldn't finish it and left it hanging for over 3 years now.
