Thanks KRae and Don'tMindMe. Presently Gen 4 and 5 are at work and school and Gen 2 spouse and Gen 3 spouse are elders and working towards being ready for Grimm.
Generation 4 has supermaxed fishing skill and maxed fishing career. He is now in the Science Career for Ops. His LTW was perfect aquarium (achieved as well), building and property have been purchased and upgraded and LTRs are in place.
Generation 5 will be a descendant of Da Vinci and supermax Sculpting with Sculpting Career and move into Business Career for ops/to keep busy. Her future husband (clone of Billy Caspian) is at Boarding School - La Fromage Art School from memory, and he is older than her.
For my final three Generations, I am thinking Alchemy, Cooking and (perhaps) Charisma. I do know that gardening, inventing, athletics and (maybe) logic are out. The three foreign skills, the time travel skills, science and social media from uni, and late night skills are still available, if difficult to complete (particularly with the very few bars I placed in Riverview).
Then again, everyone spends their home time in the garden (which is why gardening is not available for supermaxing purposes) and so while Gen 8 plants their French Grapes and picks the grapes for harvest and making nectar, the others can weed and water for Gen 8.
