Hey spankenstein89 ... A lot have people have given you good advice, but outside of not understanding why you get some repeat main Adventures, you might have hinted why you don't get new main Adventures.
World Adventures is set up with the intent of following some Adventure lines through all the Worlds available ... And certain Tombs and Adventure lines won't open unless you visit the other Worlds and follow the line. There are tombs in China that you won't access until you go to France ... Likewise, Tombs in France connected to the storyline through Egypt ... And so on. If you are mission oriented and you just want to clear one World, or one World at a time ... That's not the way World Adventures works, and you won't be following the storylines associated with the Tombs.
Best advice ... Enjoy the Worlds, gather all you can, and meet as many people as possible during your travels. Slowly advance your exploration, and you can have a well-developed base in each World long before you ever finish all the Tombs. Buy/Build houses in each World that will make extended stays more pleasant instead of sleeping in Tombs or the Base Camp.
They don't have to be complicated builds ... Here's one I built in China that's underground, and you can only get into with a dive well. and the dive well was something I picked up pieces for exploring China. Four rooms ... No walls. windows or doors ... You can add a bathroom easy enough, if your Sim is not a Witch, or hasn't completed the Carefree, Steel Bladder, Dirt Defiant, and Hardly Hungry Lifetime Rewards ... Which are recommended before you go exploring anyway ... 😆
Your Sim isn't stuck with no Tombs to explore ... They just don't want to explore the Tombs they have to in order to get to other Adventure opportunities. If you have a few days left with no Tombs open to explore in China ... Go to the dojo and start the progression towards becoming a World Champion martial artists ... Or there's a chess tables at the dojo, where you can become a World Champion chess player calling opponents to challenge, and improve your Logic Skill if nothing else.
Challenging opponents in martial arts or chess ... Improves your relationships with your opponents. Eventually your Sim will be just as much 'at home' in another World as when they are actually at home. They'll have more opportunities to earn a greater deal of money ... And they won't be so much 'on vacation' as they will be 'jet setting world travelers'.
Sorry for being so verbose ... Just trying to share knowledge and ideas with the few of us who are still exploring this awesome game ... Happy Simming ... ❤️
