I think the archeological aspiration is the hardest because you need at least 4-7 days to explore Salvadorado (however you spell it) and if the sim has kids or a job or the parent and a kid have that aspiration, it kind of interferes with the completion of that aspiration. One of my family’s has both the mom and teenage daughter with the aspiration, and when I did try to take them to Salvadorado, a sim-friend of the teen died the very first day and she was sad for a day and a half, and she was just miserable trying to complete tasks; so I tried getting some of mom’s tasks done, well you gotta take into consideration EVERYTHING you need to explore and you have to figure that out with what advice the locals give you, so I was slowed down because I had to keep going back to the market. Then the 2nd day the mom lost a friend, so then both of my Sims were miserable. And I didn’t take into account that even though you’re on vacation, that interferes with the kids schooling...the aspiration can drive you up the wall if you’re unprepared.
