People would have less difficulty playing TGO if they "spoke" to non playable character they meet in the game. If you bump into random characters they will give helpful hints similar to Arianna. For example here's three pointers, one illustrated, that appeared in the last game update to light your way:
"If you want to piss off rich people break their yard vessels"
This implicitly tells you to break open any jars, vases, pots and containers you see outside valuable properties.
(Like the Wilkes mansion, Andrea Kimura's home and Eve Cathedral for example.)
"Safes hold valuable stuff. But sometimes they just hold random metal junk."
This tell you that a safe is important to the game and probably contains something metal that you need.
(Coded instruction to look for something metal, e.g., a belt buckle, in a safe like the one in the police station maybe.)
"Dumbbells can be found in gyms. But also strong girls buy them for their homes"
View attachment 1767152
This instructs you to look for dumbbells in gyms and in the homes of "strong girls".
(Blatantly tells you to check out the two gyms in TGO, one in the Police Station and one near the Public Shop. As for "strong girls", well, Hannah trains in a gym on a regular basis, Ella also trains in a gym and does martial arts, and Carol works on a farm doing manual labour all day, every day, and is fit as a tick because of that exercise, so maybe check out their homes if you are looking for a dumbbell starting at Carol's first she being the most strapping and biggest of the three.)
Although Arianna is your main source for advice helpful pointers and hints are also available from non playable characters you meet randomly by accident or design.
Jazz along these lines can definitely help you find your way around in the game big time.
