The first tomb I built was a "Vault" for my sims to put the stuff they collected, then I made a tomb I was planning on making when WA was released, a tomb beneath Sunset Valley's library. It was fun, but surely the official tombs were better. I tried searching for tombs too on the exchange, but only found an official one and two Chinese themed tombs (If you want I can post the links).
I was thinking that France lacks tombs in comparrison to Egypt and China, perhaps if this type of challenge is done, I hope we see some tombs featuring the Eiffel Tower and the Arc de Triomphe. Hope it's done!
