I like the idea of longer research but don't want to spend half a century building a worker. So I went into the files and modded it to have normal speed unit and building production. I am not a modder and i'm not sure what all the diferent entries are for so i only modded those two.
copy this file: C:\Program Files\Firaxis Games\Sid Meier's Civilization 4\Assets\XML\GameInfo\CIV4GameSpeedInfo.xml
And put it here: C:\Documents and Settings\Joaorv\My Documents\My Games\Sid Meier's Civilization 4\CustomAssets\xml\gameinfo\
Now open it for edit with notepad and find where it says "<Type>GAMESPEED_MARATHON</Type>" it's very easy its close to the top.
Now scroll down to where it says "<iTrainPercent>" and "<iConstructPercent>" and change both values to "100". This will keep everything the same research etc etc but make the buildings and unit costs same as in the normal speed.
It works like a charm. I havent tested it for game balance but one thing is for sure i wasn't going to use Marathon speed the way it was so i'm gona give it a shot with these values. Have fun.
