I usually make a sim of my ex and then burn the house down or drown him.
I do that too. I usually make them ten times more ugly than they are in real life, too. Oh, and I make their houses nearly impossible to live in (ten ovens, a toilet in front of the television, etc.).
That's a beautiful song! Do you have even a specific theme you're looking to use? Like, Victorian or vampires or something? I would be more than happy to share some creative advice but it would help to know maybe the basic time period its set in and stuff.
I don't really have much other games on my PC right now, but I used to be a big fan of Catz/Dogz games 2-5. I was particularly fascinated by the genetics aspect of breeding them.
Pictures of the game:
They're adorable. Unfortunately, after I tried to put it on Vista it crashed right as one of the cats was having kittens. Oh well.
