How is it possible to make research take longer time by x 3??
I wonder where in the files these parameters are?

I 2nd that. Especially if you change the time scale. My scenario runs on 2 week turns not 3 week.

3 minutes later...

Actually you can reduce the # of labs players can have. This alters the time factor.

from general.txt script

/*Reseach*/
MAX_LABS 12
LAB_BUY_START_PRICE 20 /*Cost to buy First Laboratory*/
LAB_BUY_PRICE_INCREASE 10 /*Buy Cost increase per lab held*/
LAB_SELL_FACTOR 50 /*How large refund % when selling*/

Yes, in fact if you want to say halve the research rate then you can set the

MAX_LABS 6
LAB_BUY_START_PRICE 40 /*Cost to buy First Laboratory*/
LAB_BUY_PRICE_INCREASE 20 /*Buy Cost increase per lab held*/

so since the prices are doubled you are still going to have to pay the same production points to get these half amount of labs.
