Hmm, we really need to do something to get it more lively in here. I was thinking of a couple things... let me know what you think and if you might be interested.
First, a round robin. I haven't participated in one yet but from what I can gather someone starts out and when the generation is over it's passed on to someone else. No idea how the house is handled, but anyway.
Second, a building and decorating challenge. Doesn't necessarily have to be a contest... I'd be happy with just getting people involved at all. So I'm thinking maybe taking an assigned space (a particular existing Maxis lot) or just building size specifications, and make either a business or community lot. It could be anything -restaurant, clothing store, whatever- with certain guidelines (I don't know, like a water feature or something). Just... something unique. And something to do for fun.
