1. we will release some art, Alpha screenshots and other graphics and materials by the end of the month. WuS: EF site is currently under the construction
2. ah, sometime during 2008 (no one knows yet)
3. we use Ogre3D (graphic) and OpenAL (audio). the rest is ours - home-made
4. you will be able to build factories, units, upgrade infrastructure and units, build defenses in command centers... it's something between Total War and Heroes of Might and Magic, and Panzer General. A cocktail
5. The Diplomacy – well, I'll tell you only that everyone will be nicely surprised by this. We manage to create some really fresh and innovative Diplomacy model. Nothing like you saw before in strategy games.
Unfortunately, its full potential can be seen only in Multiplayer.
