I spent 4 hours creating an entire backstory/history for my character in Fallout 4. I have stuck with it in the game (18 hours in, not counting the 4 hour prep) even when it has gotten me killed on multiple occasions. I smoke the most cigarettes when creating characters, as I enjoy the outside and peace while I talk to myself and go over all of the options available to me (perks, stats, names) and I will delete a character simply because the name doesn't fit the roleplay. When I reach a point where I discover that my Roleplay doesn't make sense, or the character becomes silly, I will delete it without a moment's hesitation.
Frankly I'm surprised this character has survived this long.
Also, I love ABBA and that's nothing to be ashamed of.
