Just wondering, after the next heir is chosen/of age, can the previous heir become a vampire? Sorree if it's already been asked, but I'm just about to start and I wanted that cleared up as soon as.
Check the rules again. No family member can be a vampire. That means, as long as you control that household, no vampires. Once the heir moves out, you no longer control the previous household and whatever happens isn't your problem.
2. No household member can be a vampire, mummy, ghost, or SimBot. Any other alternate life form in future expansions is also banned.
Say you have been playing and you are getting ready to move the 3rd generation out into a new home. Can you move him into the house the 1st generation grew up in if the family living there has changed?
I would think yes because of new townies but I wasn't sure if we needed to have new homes along with townies or not.
If the founder or any of his/her family is still living there, then no. That would be returning members to the household that have already left and is against the rules. At generation 3, it's likely that the founder's family will still be there. But by generation 8, it would probably be a whole different family and your Sim would be marrying into the new family and moving into the house.
To everyone in general...
I think what some of you are missing is the fact that the only real way to move into a townie house is to marry one of the townies who live there. Even if you have a friend to move in with, you'll never get the proper interactions to make the move. The only thing you'll get is to ask that friend to move in. There's a very slim chance that the friend will ask you to move in, but it's quite rare and not enough to really use for a strategy.
As for the town losing its population, that's not going to happen. Story progression makes sure that new families move into the town regularly. There will be vampires and elderlies, true, but there will be some townies of the appropriate age. You'll just have to search thoroughly for them. But if there literally and truly is absolutely no townie to marry, then your DecaDynasty is over.
