BUG + Blue Marble + minor Civscaling.
I haven't gotten around to it yet but my changes would be:
Protective speeds building of bunkers and fallout shelters, maybe fort
Sentry for explorers
Apollo program needs electricity
Castles obsolete with corporation, and might add upkeep reduction, and reduced chance of revolt
I've not changed anything because I consider that cheating. For example, I think the Airship is a terrible addition to the game, but that is no reason for me to mod it out. That's probably because I'm multiplayer-oriented. I don't actually play many mp games lately but I do compare my games to those of some friends quite often, so everyone needs to have the same game.
But of course I use Bhruics patch, like everyone else.
