The fortune cookie one is actually nothing to do with personality, it just means they have a tidbit of info to give you (stuff from PLOT_FortuneCookie.txt). Basic advice like:
"If you specialize in armed combat, you might want to think about getting a boomerang or a spear so you'll have a missile attack which uses your best skill."
and humorous (yet true!) stuff like:
"If you would be a great warrior, you must battle through the cave naked, armed only with a toothpick."
Some of it tells you things you can do in an indirect way, like:
"Scientists spend too much time looking at rocks." (you can use science on rocks to inspect them for valuable minerals)
I just had the most epic mission. One of the plot missions where I have to invade a lab to steal the enemy's secret mecha design. It was a basic combat mission in person where I had to fight my way through their lab, activate several computers to activate the mech, release the mech, open the bay doors, etc, then run to the mecha bay to steal the bot. Only most of this stuff was behind secret doors, and after activating everything I couldnt find the mecha bay itself. While searching for it an npc with a rocket launcher attacked me, and this set fire to the building (it was a space lab, but I guess all the walls and floor were flammable). Soon the entire place was a raging inferno, with me dodging fires and running ahead of the fire frantically searching for the mecha bay. All the monsters were burning to death, and all the walls were burning down and turning into walkable tiles.
I eventually had to double back (I ran out of map, EVERYTHING was on fire except the tiny bit of space I was in) and sprint through the fire. I emerged on the other side (apparently after it burnt up, it was safe to walk on - weird green looking tiles after the fire had finished with it) with only 2 hp left and my armor was pretty much shot from the burning. Safely on the other side, I walked to the places I hadn't explored yet on the map (and could not access before due to not finding the secret door) and found the mecha bay tucked into a corner as a free standing door with all the walls around it burnt up. I never did find that secret door, but mission success! It gave me a pretty badass dueling Vadel worth over 1 mil with a "master cannon" gun. DC9x10, 32-64-96 range, ACC:+2, SPD:3, 50 ammo, overload, armorpiercing, and antiair.
