and big red eyesIf you're going to switch civics, almost completing one of each unit and then finishing them after you switch gives you higher exp units.
Well I used to play civ 1,
In civ1 you could start to build a useless wonder and get nearly finished, at the same time be heading for a tech that would you the option of building the wonder you really wanted to build, then you could quit the build on the previous wonder and all the hammers would be transferred to the new wonder,
wilzi,
On higher difficulties of Civ 1 there were penalties for swapping buildings in mid-production, which made it not quite so useful.
If that's not it, I have no idea what the cheat is. I mean, some people think 2 pop whips are cheating.
