Hehe, I've been waiting for one of these.... My ultimate strategy game would be something along the lines of Frontier, but in a much bigger universe.
I'd include plenty of astrological phenomena (ie nebulae, black holes etc) and make the universe dynamic - i.e. constantly evolving. I'd have many more ships, alien races to interact with - and who also interact with each other, and expand the missions to include exploration as well as conflict.
Ideally, there would be an option for network gaming - either as a deathmatch in a single arena or a co-operative team effort.
And I'd have to get a little "creative" with the game's interpretation of physics so that combat is much improved......
Any takers?
:-D :-D
