I'm glad you enjoyed the video. I must admit a few things happened during this episode that surprised me, but I thought it would be fun to go with them. I've now recorded video of Carl being cured. The hint I can give without giving too much away is that it involved sims from The Isla Paradiso Bunch. So expect to see some of them in the next episode.
Mods definitely help to customise game play.
Years ago, long before I added mods to my game, I stopped playing with families as the family trees used to break and toddlers regularly became strangers to their parents. So I used to make households of eight unrelated young adults - four male and four female. There was no romance between them. I used to build a huge house and fill it with stuff and decide what skills they'd learn and direct them to learn those skills specifically plus whatever else I thought of doing while playing their household. Mostly I would just watch what they'd get up to. After a while they would get to level 10 in several skills and I'd want to make another set of 8 young adults. As a result, I ended up with a lot of highly skilled young adults and when I added mods and started playing bigger games and actually having my sims go out and explore worlds I found a use for those highly skilled young adults. I do give them makeovers since I have custom skins and hair now, but mostly I just plonk them down into houses and give them free will and my sims come across them occasionally and they are often found to be doing some interesting things. I enjoy seeing old familiar sims around town instead of game generated townies.
That graduation was a bit of a mess. I came across Mary wearing her graduation robes at home. Then I discovered Barbara was at City Hall graduating. I probably should have shut down and tried again but I let it progress. In the end both of them ended up with diplomas but Mary didn't get any awards to hang on the wall. Barbara got everything they usually get. I'll have to check if Martin and Bart have their diplomas. I'll probably have to play in that world for a few sim days before it will offer them the opportunity to graduate. Currently I'm focusing on trying to get the main household to start Generation 3. And I don't want the game to add too many extra sims to that world. I'm not sure how many furnished houses are in it. The world was not completed and most of the buildings are just shells with nothing at all inside - they still have grass floors. So I'm hoping not too many extra sims will be able to move into the empty houses.
