@Erin,my sim was with Johnny Zest too,they even get married
Well,I feel a bit strange,hope I did nothing against the rules...here is my strategy:
First,I listed all the possible upgrades in the game in a testing file.
I bought all objects I could think of,and,with a sim who was at level 10 in Handiness,clicked on them,and listed the exact names of the possible upgrades (my game is in French,hope they are not different in English!)
I didn’t know about many of those upgrades,so this was really interesting ! For an example,I didn’t even know that it was possible to upgrade beds…
I finally listed more than hundred of possible UU in the game.
Then,I tried to find the objects to upgrade on community and residential lots,and made a little list of some I will be able to find and upgrade outside my home,without having to buy them.
I planned to buy only the objects that aren’t on existing lots in the game and try to upgrade the most possible objects outside the house.
For the woodworking part,I tested too,and found that it would be more profitable to make my sim concentrate on the few expensivest ones :
1) mascot camping sculptures
2) bathtubs
3) guitars (I had to spend time learning guitar until I was level 8 but I think it was worth the time)
4) dining tables
I was thinking of learning and making violins too,but finally abandoned the idea.
I spent 4 entire days (24 hours non stop) making those 4 items again and again.
The other days were spent doing upgrades and gaining satisfaction points,in order to get potions (my sim never ate nor slept) and the marketable trait.
The first days,I learned guitar too,and leveled a bit the handiness skill.
I didn’t buy a house,I put my sim on a 20x15 empty lot,made it a «tiny house» (lowest bills, faster learning of all skills),put the lot traits «study spot» (to learn the skills faster),«home studio» (to make better quality items), «great acoustics» (only when I was learning guitar) and «homey» (to level handiness faster).
I bought a lamp to be concentrated while woodworking,and another to be inspired while playing guitar.
I bought a desk with a chair and a PC too,to be able to order handiness parts,a radio,a bush for toilets,and a tiny house bed.
My sim was a genius,cheerful and music lover.
At the beginning of the game,I placed the Shimuzu restaurant (because of the outdoor lamps that can be upgraded) and a spa (to make an upgrade to the sauna,which I didn’t buy for my sim because it’s too expensive).
Here are the details of my 14 working days:
D1:gaining satisfaction points (level 1 of vampire aspirations+musical genius 2/4) to buy potions,learning guitar until level 8 (ok at 6:00 am at the end of day 1)
D2:gaining satisfaction points (soulmate with Johnny Zest)+begin leveling handiness by woodworking (2 horses sculptures,1 garden planter,3 mirrors,12 wall hangings )
D3:handiness was nearly level 10. I continued gaining satisfaction points with soulmate aspiration and began UU outside the house. I sometimes did the « get the pieces » interaction (not sure if it is entitled so in English) on electronic devices outside the house,to get free handiness parts. Then I went to Granite Falls and learned to make the mascot camping sculpture. Then,made toilets to get 100 satisfaction points (it was a whim). Made 6 UU outside the house and 2 inside (on tiny house bed) this day.
D4 : making 35 mascot camping sculptures and gaining satisfaction points (fabulously wealthy 3/4)
D5:gaining satisfaction points (soulmate)+7 UU outside the house
D6 :9 UU outside the home+1 UU inside (I bought the meteo machine because you can make 7 UU on it)
D7 :making 20 guitars (47855 $)
D8 : gaining satisfaction points (soulmate) +10 UU outside the house and 1UU inside (meteo machine)
D9 : making 20 bathtubs
D10: 1 UU at home (meteo machine)+ 9 UU outside
D11 : 4 UU outside+ 13 UU at home (4 on meteo machine+ 3 on talking toilets+ 6 on vacuum cleaner)
D12 : 18 UU at home (2 on automatic sprinkler,1 on clothesline,5 on washing-machine,3 on drone,3 on gaming console,3 on dishwasher,1 on tumble dryer)
D13 : making 21 dining tables
D14 : 14 UU at home (3 on karaoke machine,3 on microscope,2 on video production station,1 on bowling alley,2 on x-ray machine,2 on whirlpool,1 on drawing tablet)+ making 2 end tables because I had a little time left
The UU I made outside the house were on beds (2), showers, bathtubs,corner bathtubs (the upgrades are different than the ones on the classic bathtubs),toilets,sinks,stoves,fridges,microwaves,coffee makers,tea pots,observatories (at San Myshuno park and at the Geekcon),talking toilets (San Myshuno),fireplaces,video playmats (Behr and Lobo),coffee machine ( Bjergsen),PC,TV,dishwasher (Hecking) and surgery machine for pets (at the clinic in Brindelton Bay).
If anyone is interested I can provide the list of the 95 UU I made but it’s in french.
