Researching Global Prosperity

[Nutz]

Hi all,

I was just wondering how you research global prosperity or those other end of game researches??

I have the Thrones and Patriots expansoin pack. I have researched all the techs I can but when I go to the library there are no further options for me??? This is in a campaign game vs the computer during the information age. Are you not allowed stealth bombers in campaign map games?

what am I doing wrong? I have also been using nukes, is this a penalty tha applies?

Thanks in advance.

You can't invent those 4 special research in campaigns IIRC, only in "normal" games

The penality with nukes is if you're using too many of those then the game will be lost (look at the number in the upper-right corner)
