McShay.. after all my years of playing I have yet to see a player working 3+ Spaceports in a multiplayer game.
I sincerely doubt it would last that long, even if you play to mark 2000, 6 spaceports are a bit much
okay, now I know which of the older players I haven't been in a game with yet
On la corr, it is VERY easy to mass-missle. In one game, I hadseven space ports up, all building missles while I was panic-producing tigers for defence (had a swarm of emp + Thor tigers from an opponent heading towards me). Fired missles 1 after another in acircular pattern aroundthe army, and had more than enough ore to build anouther round and keep up my tiger production. The bottleneck saved me on that game, heh
and MD have a lot of issues. If you have 2 too close to eachother, they can't hit anything (I learned this on the eden campeigne. I huge meteor was hading right between two MD's, both fired, both missed)
