Again, basically, the slider is fine. All other effects work as intended, and in the correct orientation. The only flaw is with production efficiency, that is, it's reversed from the old and intended effect. As you become more decentralized, your production income will rise. This does not, however, in most cases offset the advantage of being centralized (lower tech cost), but it certainly brings about a closer parity, and I think especially for multiplayer, decentralization is now a must. All this changes in 1.06, though, and I'll be very thankful for it. I don't like exploiting the game like this, but since my MP opponents will surely do it . . . . so must I.
