Rank system
 

I found very intesting the rank system used for the campaign battle; i fund also that the point are save in the profiles.cfg file also for the custom battle (but linked to the map, so if play two times over the same map I deleted the first battle points, why don't use a true log for each battle played?). Also for the multiplayer battle exist the point system? (very useful for ladder)

No.
But in the ladder will be rank system. ;)

Thank Marian.

But when the demo and the lobby will be ready? 10 days, 15 ? I make much publicity to game in the italian total war fans group, but many wait the demo and the lobby before purchase the game.

Now we are busy at the prosecution of add-on. Only in add-on there will be ladder.
Demo will appear since we will finish add-on.

A part from lobby and corrections, in the addon we will find also changes in factions or units?

Some units will be changed. Basically animation, physics, the game mechanics of game will undergo to processing. It will essentially change game and gameplay.
