For everyone, when making a new game(sequel) for another (in this case for the families or villagers series), would be a good idea to continue with the timeline and not throwing it to the trash.
For example: for a VF sequel could be like," following generations and generations(acually one, if the VF series happens in the real life around the 19-20th century), the life started to decline(VV4?) and then, your little friends wanted a new ,better; new home(VV1?) and it's your job to make a ruined house into a mansion!; or just, one of the generations win a lottery price and buy a new house", ect.
