I chose the following traits for my Sim:Adventurous – So he could go on another trip sooner. (at least I think that's how it works)
Disciplined – So he could learn the martial arts skill faster.
Genius – So he could learn the logic skill faster.
Over-Emotional – So that all his moodlets contribute more to his mood.
Lucky – To help him win more than lose in both the martial arts and chess tournaments. (It help with the chess tournaments but with the martial tournaments it was not helping at all, in the begin I lost more than win)
I decided not to waste time increasing his skills, since he will be given opponents matched to his level. This turned out to be true for chess, but he lost 19 sparring matches!
As soon as the challenge started, I sent my Sim to the Library to learn the logic skill, and straight away sent him to China to learn the martial arts skill. That way, when he was waiting for a chess opponent in Sunset Valley, he could practice the martial arts skill, meditating in between and sleeping, eating, socializing, etc
As soon as I got there, I also took all the books from the bookshelves so that I could sell them when I got back to Sunset Valley. It also meant I could afford to travel faster, now with more money.
I bought a tent, the martial art dummy plenty of showers-in-a-can and high quality dried food. I went for the high quality food because of the +20 moodlet that lasts for 2 hours. He stayed at the academy for the entire first trip.
My strategy was similar with most of the other players, but most of the time I was sleeping in my tent and ate the high quality dried food. I tried it both ways the base camp and in the end I preferred the academy. Sure there's the only1 bathroom issue and everyone creating a log jam in the entrance but there's no fridge which I also found helpful.
I read through allot of strategies here and must say I have learned allot and will try them out myself next time. Good job everyone and congratulations on all your high scores.
