As a newbie, I'm playing SP on RMs and in the Achievements section, I notice that I always have many more technologies than the Computer civs; sometimes I have more than twice their techs. Am I overdoing the upgrades or is the AI not a big fan of upgrades?
A second question, if I may: when designing scenarios, is there a guide to how many resources you should include, or is it just one of those "test and see" variables?
And Carthage must be destroyed.
