I do graphic design too... I've been involved in a 2D-topdown shooter like Alien Breed From Team17, And done all the graphics for it so if I can be at any assistance I would like to help you out or any other that needs graphics done (In reasonble amount of work for one person ofcourse :-))
I agree with the idea of more strategy and less keyboard and mouse action :-)
Hmm... A good strategy game to me has cool but not dominating graphics, it has cool ambient and effect sounds, smart enemies = good AI... A multiplayer internet and LAN game would be great and cdda support if people want to listen to their own music
