I need tech cost confirmation

[Adam7Eight]

Guys, forgive me, I'm having brain cramps here.

I want to make techs more expensive than they are at default after other civs have already researched them. Once they're known, they're too cheap to get, IMO. So, in the GlobalDefines.xml do I raise or lower the value for "TECH_COST_KNOWN_PREREQ_MODIFIER":

<Define>
		<DefineName>TECH_COST_KNOWN_PREREQ_MODIFIER</DefineName>
		<iDefineIntVal>25</iDefineIntVal>
	</Define>

If I want them to take longer to research I lower the value, correct?

You'd have to test it to be certain but if it's like the other modifiers out there lower is quicker, or more like 25 is 25% of the actual cost defined in the tech file. Well, after all of the other modifiers... anyway, I would guess anything over 100 would make it take longer to research, that's how it works in the era and game speed files.

Yeah, I just tested it for a while. A higher number was what I was looking for.
