I was really good at this game, using my spies to take over enemy cities for money and take over the world in a really passive-aggressive manner. But the best bit from the CD-ROM version was the talking advisors who would give you funny and often contradictory advice and bicker with each other.

It’s still one of the best games ever made, and there’s some good freeware clones of it about, so give it a try if you hate having spare time at all.
