Premade households - Who should i play with?

I'd play the Roomies, for the reason that they seem to be a nicely diverse bunch gameplaywise. Ideally I'd give each a partner from outside the household, thus sparking five households. But since you want only three additional households, you could pair some of the Roomies up with each other. In any case your three new households all originating from the Roomies gives them a shared backstory, what is something I value in rotational saves.

I like to play with the Goths, I don't know when it started but everytime I end up in that house I feel like Gunther isn't appreciated by his wife and I'll make someone to make him happy. He's a good dad and cleans up nicely both in appearance and if you fix his work or just get him a new job. Fun I think.

You know me, @texxx78 - It's one of these three: River McIrish, Bebe Hart or Samantha Gray. (The first two are in Sunset Valley, the last is at University).

River McIrish, usually, being the winner.
