Roland Johansen said:It was fixed in Warlords (and I'm happy that it was because I really hated the micromanagement that was connected with it but it was to powerful not to use it).
The first turn of construction has a 50% penalty connected to it.
(The following assumes normal speed)
If you pop rush an archer with 5/30 hammers, then it will cost 1 pop and give you an archer with 35/30 hammers (so each pop gives you 30 hammers). If you pop rush an archer with 0/30 hammers, then it will cost you 2 pop and give you an archer with 40/30 hammers (so each pop only gives 20 (=30/1.5) hammers).
If you rush buy a granary with 10/60 hammers, then it will cost 3* 50 = 150 gold. If you rush buy a granary with 0/60 hammers, then it will cost 3*1.5*60=270 gold.
The pop rushing and rush buying always complete finishes the project in production. So you'll always have that turns production in overflow and with pop rushing, usually there will be some additional overflow as you cannot sacrifice a partial pop.
There also exist some cost multipliers connected with the various small and great wonders in the game. They are not all the same and vary from 50% (early game small wonders) to 300% (late game wonders connected to the space race). It would go to far to list them all here. If you are interested in a particular penalty, then you can find it in the file CIV4BuildingInfos.xml. The file lists the various buildings one after the other and each has an entry called iHurryCostModifier which determines the additional costs for hurrying that small/great wonder.
Edit: There is a difference between pop rushing and rush buying that I forgot to mention. Pop rushing production is subject to production bonusses in the city. Rush buying production is not subject to these production bonusses.
The penalty is really significant. I guess it's always worth having at least 1 turn of production before rushing, unless it's an emergency.
I had noticed the penalty with rushing wonders. I guess unless you really think you will lose the wonder this is perhaps not the best way to rush them (but I will check the list). It makes forest chops even more important for rushing wonders.
You explained earlier that rush buying is indirectly subject to production bonuses. I.e. each hammer always costs 3 gold, it is just modified in the normal way. So I don't understand your last comment.
Thanks once again,
