My one concern about the whole thing is that just killing mob upon mob of space jerks might become tedious over the span of an entire game, regardless of how compelling the story may be, but some variety down the line amongst what you have to kill, be it new and intersting ork classes, or entirely new enemy forces, might keep things fresh enough to slog through the whole thing.
All in all, I'm not sure if I'm sold on the game, but I definitely feel like checking out the full release via rental or bumming it off any friends who pick it up once it comes out. The demo itself makes for a great stress reliever even if it doesn't get you any more interested in the game, and is worth blowing through a few times before kicking it off your hdd.
