I think he sold his sceneries outside simMarket and others because of piracy. Some Brazilians, no offense, like a free lunch now and then and some previous works Paulo did ended up in some blog sites. I must assume that to avoid this he marked some files and when it ended in some torrent or blog sites he would know where the leak came from. I bought all 5 packages he made, including Mega Rio, and received them by mail. It was so fantastic that I had to buy the one in simMarket. Yes, now I have two copies of the same scenery, but what Paulo did goes beyond what you usually see and get from other developers and for a very, in my opinion, low price. The great thing is that Paulo promised more and more updates for this scenery and he's just one guy doing this. Well, now he's gone global and I do wish he sells a lot.
Cheers,
Joe
