Aspirations

• Party makes you recover twice the sanity you'd usually get when using objects -Fortune needs investigation
• Popularity and Romance seem useless for Any%

Skillpoints

• Creativity increases the cost (and maybe the rate) of your paintings. It may also impact the tips you get while mixing
• Charisma doesn't seem to change the amount of actions required to calm down other sims (maybe after reloading the game)
• Business needs investigation
• Mechanical's only use is to hack the elevator
• Body seems useless for Any%

Glitches/Exploits

• Running diagonally is 40% faster than running forwards
• The dizziness effect preventing you from running (after dying in desert) can be bypassed by opening the Super Drencher or Ratticator menus
• A skillpoint can be duped by drenching it before picking it up. It will be back when the area is reloaded
• Sometimes, paintings from a previous game stay in the art gallery after a new game
• Clicking menu buttons right when they are displayed can do weird things, like bypassing the painting confirmation pop-up (and maybe more?)
• You can hit enemies with the Ratticator abilities when they are at a different height than you
• There is a glitch to get a lot of money at the start of the game but I cannot reproduce it and it seems to lock the story (other source) (edit I got it once)

Misc

• You can select the interaction you want by holding A and using the D-pad instead of using the touchscreen
• Reloading the room is enough for the antagonist to be in the state to give you the next goal, no need to wait for the call (except for the first call)
• You don't need to go through the dialogs before calming/cheering up Honest, Frankie or Tristan
• Changing the clock settings is faster on DS than on 3DS (idk about the DSi)
• The original DS seems to lag more than the DS Lite (especially during fights)
• Weather is always the same at a specific moment
• You always get a phone call from the Concierge if you load a save that is from just over 24 hours ago, the call is even longer after a week -According to the Concierge, some guests tend to give more money for their stay (needs investigation) -Collectibles placement is set every game launch and is the same on all save slots and new games, so if you take a nuclear rod and reset the run, it will be gone until you restart the game completely
• There's no known way to completely reset a cartridge or delete a save file without homebrew or modding, making potential categories such as All Secrets%, All Concept Arts% or 100% less accessible
