Nikitachi had an amazing score in this one...not just a little more money to secure the win, but leaps and bounds in front of everyone else. Well done.
It's too early to congratulate me, since, as I said, I am not sure whether I did a legal thing in this challenge. Usually I always ask the team, but this time I was playing on the very last day, so I could not wait for the answers.
If I broke the rules, then please remove my score and mark me as DNF, if possible.
Actually, for my strategy, it didn't really matter what do you use to earn money in 19 days of 20. The only day that matters is the last one, and it brought me over 2 million.
My trick was growing Money trees. I bought the first one from the rewards store (5,000 Satisfaction points) in the beginning of the game, as soon as I could, and planted it. When it gave fruits, I didn't gather them (because this results in instant money), but instead I put the whole tree into Family inventory. When you do this, it automatically turns into a separate tree and 5 new Money tree seeds. Then you just put the tree back and plant the seeds, waiting for all these to grow, and then repeat and repeat... Also, I caught some good fish to fertilize and speed things up. I ended up with the whole lot covered in Money trees and finally let my sim collect all the grown fruits on Day 20.
Since I didn't get any simoleons while planting and growing the trees, I considered it to be okay. Specifically:
You choose 20 unique ways to make money, and you do them each for 1 day only.
The way was "gathering money tree fruits", and I only did this on Day 20. On other days, I just put the trees in the inventory which I consider to be another activity.
However you choose to make money each day, that is the ONLY thing you can do to get money that day.
I only got money from money tree fruits on Day 20. On other days, these activities gave me 0 simoleons.
Items you make or collect to sell must be made/collected and sold on the same 1 day, and that is the only day you can do that activity.
Technically, with Money tree fruits, you can't collect (aka gather) the fruits with sim's hands and choose whether to store or sell - they turn into money automatically. So, on other days, I didn't really collect the fruits, and even if I did by using the family inventory, I wasn't going to ever sell these fruits - I was only going to plang them.
Thus being known, I am now awaiting for the team's verdict.
Anyway, it was great to try this method!
