In the last multiplayer run of Diablo II I made a couple years back, my necromancer was naturally named Rufus. My druid was named Rhizome. There was an amazon named Tribs.
I took a run around WoW for a little while, and most of the little characters I made had proper names for their races, but when we made up a pair of dwarves just to play through classes we hadn't tried, they were named Gulnyr and Argali. Dwarves are so godawfully ugly they didn't get past level 4, but still. The thought was there!
I don't remember which Sims game it was, probably the first, everyone had modded the teeth out of it with what seemed a thousand gigs of custom content, and I was using it to slowly making my little neighborhood of Layonara. I had the children > halflings mod that let them live as miniature adults in hill houses. What is disturbing about this is that this was around the time I was playing Layonara 24/7 anyway, so imagine my brief off-time being spent creating it in miniature. Like I said, disturbing. Anyway.
I never really played the game, just made little neighborhoods and scoured the internet for ways to break it. I don't know why. I try to steer clear of Sims games for this reason. I did briefly play one of the newer ones and recreated several Layonara people, and was alarmed at how the traits system made them really act a lot like the characters they were inspired by.
