Aethon is hillarious. Take him to the mint in Cademia and see what he says. Also, take him to either the Cademia or Odemia jail. It is also amusing to talk to a tavern owner while Aethon is present.
Use a gavel.
Get every item.
Explore the "killing a sleeping person" glitch and see what kind of strange item they turn into.
Talk to "Nothing", the strange, dead, invisible person in the northwest corner of every map, who you can kill over and over again.
Try the little-known "real time" mode. It doesn't work very well, but it's interesting. To toggle it on and off, hold option and press the spacebar. I found it by accident.
Talk to the ghosts in Abydos at night.
Kill Magpie.
Kill everyone.
Use the Wishing Fountain.
A little easter egg - ask people about Gene - it's an easter egg referencing Gene Leonard, who is mentioned in the credits.
Try using different fountains. Some locations have unique responses - the fountain in the cave below the Cademia sewers mentions something about the mineral content being high, the one in the grotto below Kosha is salt water (Sort of a clue), and the one in the Scylla Temple is poisonous. There may be others.
Feel free to add to the list.
