A good name and a good story. I find that using The Sims system, but also having a broader story in my imagination, works out the best. Plans, whims and coincidences come together to give me a different story to the one I intended. (I love how the new preferences system derails some plans I have: my gardener hates gardening, which I choose to accept and go another way.
My fave sims:
* Lectern Colliery is a mean-ass tory. He was meant to be a crime lord, but fell out of crime and became prime minister, or at least head of state. He dresses like an Edwardian landowner, and he intended to have his underling Dooley (a snout-faced magician pickpocket) kill Count Vlad, so they could take his mansion and make it a crime HQ, but a social media influencer beat them to it, and repainted the place in all garish colours.
Lectern Colliery's favourite habit is whirlwind romances resulting in pregnancies. He'll turn up at the door, woo you, bed you, and never come back to meet the resulting child. (I do not endorse this, but it suits him. There are two generations of Colliery-Goths in my game). My current fave, Azo King is doing the same in reverse, raising a brood of famous folk's lovechildren.
* Rutger Bubble is a short, immensely plump, green-skinned gardener. He only wears bright yellow, with a propensity for jumpsuits and broad-brimmed hats. He's a well-beloved celebrity (not really famous *for* anything, just famous in general). He knows everyone, and everyone knows him. He lives in a small, futuristic house with a big garden with his magical husband (every home should have one). I rarely play him, but often befriend him.
