Wow! a Moroccan world this doesn't come along very often. It looks amazing. I could TRY and help make Sims but i'm not promising anything... and they might not be very good. When you do need Sims just list down what Sims you want in a family and i'll try my hardest to make a Sim. Again it might not be any good though
I love the distant terrain in the second last photo it looks amazing with the waterfalls, hills and trees. Good job on this world Ps Do you have a name for the world?
Are you making your town like the Pleasentview from The Sims 2 or a completely different town? If it is a different town then I'd suggest changing the name to something else but I'd suggest calling them ideas from what other people have said.
I get the 'Unknown Error Ocuured' message as well but it's only when I click on the Late Night shortcut. Are you clicking on the Late Night shortcut? Try another shortcut and it might work. Just a suggestion
