Bit of a tangent here, but I recall Larry Harris (the game designer) indicating that if he were to make the next version of A&A that he only wanted capitals to be able to build things; he didn’t like the idea of being able to freely move IPCs around the world to make 3 bombers in India for instance. I think the idea is that complexes increase the value of the territory instead of being able to produce there, which is interesting. But remember this is all speculation from a couple years old post.
That would be interesting….planning strats to attack the enemy supply lines, if u only could place units in
capitals, the supply lines will be both long, thin and vulnerable
