I think everybody knows what "The Sims 3" is so I'm not going to tell you here about it but, I'll tell about the expansion pack "The Sims 3 World Adventures".
"The Sims 3 World Adventures" is the first expansion pack ever. It gives you the feature to travel to another countries like China, Egipt and France. Of course it gives you more furniture like all other expansion packs and new skills so it is pretty cool :)
When you go to other countries you'll accommodate to a base camp named... "Base Camp" and don't forget to buy some souvenirs from the merchants because they sell stuff that you can't buy only there. If you go in any of these countries you can discover secret doors to find the treasure but, it's not as easy as you think. You can accidentally fall in a trap and even die.
You can earn some Ancient Coins to purchase Special Adventure Rewards, Collectable Relics to place them in your house and you have to earn VISA points to make your vacantion longer. First time when you go you'll stay 3 days. The second level is 5 days. The third level is 8 days. The fourth level is 10. The fifth level is 12 days.
