Preparing for release day on the Galactic Civilizations II Website (thanks Frans) is a diary entry related to completion of the space strategy sequel, including preparations for digital distribution, as well as a bit on plans for a demo:

The demo version obviously needs to get done. A lot of people won't buy a game without at least trying out the demo. The demo won't show up before release though. We want all our development effort put first to the people who are buying the game sight unseen. Those people have put faith that we'll treat them well and I want to make sure we do what we can to make sure they feel like they aren't let down.

So once the game's released, we can put together a demo pretty quickly. Even though the game requires 2 CDs to install, I really am hoping we can put together a demo that is less than a 200 meg download. Maybe even less than 100 megs. The tough part will be deciding what's in the demo.
