Is Dungeon Siege 2 demo download a FULL game?

[Vancomycin]

I am downloading the demo of this game but it is huge. The demo is 1.39 GB big.

Is the demo a full version size except that it is a demo because you need to activate it to play full version? I see this type of small game demos in which they are full size but you have to enter the serial number to activate it into a full game.

Is Dungeon Siege 2 the same way? I ask because that demo size is HUGE.

For those who bought the full game at the store....how big is it? does it come in 2 CD's and about 1.39 GB big?

The whole game is 2,290MB from the add remove programs list in Control Panal.
