Internet Connection Neede to Install?

I have not purchased Napoleaon Total War even though I am a TW fan and play Medieval TW and Rome TW (and several mods) often.

I would like to purchase and install Napolen TW; but I notice the game box states that an internet connection is needed to execute the installation. My PC is a stand-alone PC with no internet connection.

My questions:
(1) Is the internet connectiontruly needed to install Napoleon TW?
(2) If yes, is a web ser needed to complete the installation?

Thanks.

You need an internet connection to activate the game via Steam to install it and get the updates. There is no way around it.
