I don't put a Sim based on myself in the game, I have done it a couple of times via a friend's request, but I avoided that household afterwards. Never have been a fan of naming characters after myself in other games either.
I spend more time creating families, or coming up with ideas for what my town will consist of versus actually playing the game, which I find kind of lacking, but putting a character in it makes it less so. What I mean is that instead of a Sim doing a random act, a Sim Elsa is doing that task kind of thing. It makes the game a bit more fun for me.
