Something similar to iMobsters ...
 

If you've played imobster before you'll know what i'm talking about. If you haven't you should be able to obtain enough information on google, and member feedback to make it work.

I was thinking earlier today to myself, how fun & competitive it would be if someone designed a plugin/mod that allowed members to basically play a mini form of imobster, but within there own community.
Try to get it as close to the real deal as possible without stepping on any copyright infringement laws.

The only change i'd really suggest from the original game, would be to allow members to form alliances, & families. Right now in the game itself you have to leave a comment in order to link to one another... sort of annoying.

If it is as good as the game itself, which is pretty simple in nature... it will be a smash. :)
Or does something like this already exist?

Thanks...
