Just wanted to give an update ... I think the Avengers are likely to be the most successful for me.
Agnes has just died in game on Sunday of week 9 (the current day). She is the first death in the family, and was approximately 100.
Marty and Justine Keaton are both over 90 so they'll probably be dying soonish.
Founder is immortal, Gen 2 turns Adult on Monday of week 9 and Gen 3 became a teen on Saturday of week 8. His IF was turned real and as both are teens, they are boyfriend/girlfriend. Following Agnes' death, I have 7 in the household, so enough space for Gen 4 to be born as soon as they are adults. I'm having to watch Gen 3 like a hawk, particularly in China for his martial arts contests. He is forever wanting to go to the chess table and learn logic, which would kind of wreck Gen 1's supermax of logic.
Gen 2 has adult/elder museum portraits, 1 or 2 opps and best friends to go. All the rest of her immortal needs are already completed.
Items for Gen 4's supermax of handiness are being gathered. Lots of broken computers, sinks, dishwashers, all in one toilets and more behind a locked gate means he'll repair the 10 plumbing/electrical items in a breeze.
So, hopefully things will continue to go nicely for me. Oh and I'm doing lots and lots of backups so that I hopefully will get through this time, and failure will be due to silliness on my part, not on computer glitches.
