I had put up this issue in the pictured thread, but I think that I should post a proper classification of Nile Delta in this thread, and how mucked up it is.
So far, I have seen two screenshots and one trailer showing the Nile Delta. But as it turns out, they don't look like the real Nile Delta at all! They look mostly like a lush region sitting in the middle of desert with a single, awkwardly large river running through. CA probably ignored the fact that Nile Delta comprises of several rivers branching off when it is just about to join the Mediterranean. I can barely spot a little stream running off from this.
Here are the screenshots:
There is the Cleopatra trailer which shows the Nile Delta. Look at 0:32 seconds for a proper view. I was not able to embed the video, TWC doesn't allow proper embedding now.
And here is how it looked in Rome Total War:
And Medieval II Total War:
And Empire:
And finally Napoleon, which undoubtedly has the greatest detail of the Nile Delta ever in a TW game:
Sorry for not all regions being seen properly in Napoleon screenshot, as I have not revealed that much of area. Again, I took these pics just to show you in a hurry last 5 minutes, so please forgive me for the bad quality. 
So, did you spot the difference? It looks very lame compared to the detail shown in previous titles. I guess they wanted to allow the players to sail their fleets in the river, but it is too large to be a river. And no branching rivers, which are the true reason for the fertile lush in the islands that lie in between.
Someone has raised this issue already on Totalwar Forums. And surprisingly, his name also turns out to be having the word 'Maximus' in his name....what a coincidence. But that's not me for sure. 
So CA, I beg you, please fix this. I was very confident about this game, but this looks utterly stupid and can be a game breaker for someone who like accurate geography, such as me.
