I hope there will be a tutorial explaining the basics that goes with it, whether it be a trailer or a video included in the demo. Remember all the backlash when the game launched? I for one will be hosting a server to help new players when the demo comes out.

Also, trailers are the most effective way to get your game noticed. Demo? Trailer. Patch 1.2? Trailer. New Demigods? Definitely trailers. When you release a video, you force game sites to notice it and post it. And the game just looks so cool, I could be sold on the graphics alone. The original trailer is great, but it was released way before the game came out. Maybe try using the new replay abilities to show some really intense in-game footage? What about Demigod: Battle Reports a la Starcraft?
