Limit in playing Demo?

[Lord_Guilherme]

Will there be a limit playing the demo? I mean, will there be things like: "Demo won't be playable 1 week after installing", "Demo won't be playable after the X day" or "Demo won't be playable after 30 game matches"?
I'm worried about that because I probably won't be able to buy the full game so soon like you European guys (probably I will ask an auntie that lives in USA to import it from Europe and then send to Brazil), so I will need to satisfy myself with the demo while the full game doesn't reach my PC...

Afaik the game ends after you conquer five provinces, your second monarch dies or perhaps, if you manage to gather all of the Kingdom advantages.

I know that.
I was just wondering if there is a limit to be able to access the demo (like Age of Mithology Trial Version, which you couldn't play after November and had to change the date of my computer).
